content: I'd recommend Windows 7 Professional or Ultimate Edition (64 bits) with a Windows XP Virtual Machine (32 bits).You could run any software/hardware by using that combination.

content: if it is just for electronics and it's not the most powerful 64 bit system with over 3.5 GB of RAM I'd go for XP 32 bit, from what I hear xp 64 bit was a bit of a fars because by then Vista was on the way and the driver coverage for XP64 was not great as manufacturers turned to vista.many slight older and freeware programs are more likely to work on XP than vista/7

content: I work on Win7, 64 bit, 2GB ram, 500GB HD... it's a very reliable OS. Don't think Win7 is as bad as Vista, you should try it before discarding it.Vista is a RAM eating monster. Win7 is not.If you have 4GB, you will barely use virtual memory on 7.I run heavy software such as Matlab, Labview, Altium, MPLAB, Full HD video playback, etc.

content: 7 is ok but to be honest neither 7 or vista have brought anything more than XP apart from 64 bit support, if you want a snappier system and don't mind loosing 1/2 - 3/4 GB of ram go XP, if you want all the flashy stuff and the ultimate windows ad-ons like their new messenger that will "only work on 7" (so that you are forced to buy 7) go for 7

It was an OK solution when it was the only 64-bit desktop Windows version, but not today. I don't like to roll out any new Windows XP 32-bit systems either, but at least that's acceptable for old hardware or supporting legacy software. Anything needing a 64-bit OS should have no problems with Windows 7, however.

content: I ran XP Pro on my old box and, after some minor upgrades (very minor) I got 7 32 bit. It starts and shuts down waaaaay faster than XP and seems very stable. The difference in my CPU isn't big enough to explain the start and shutdown times, so it has to be the system. There are some drivers I haven't found yet (old Adaptec SCSI card for scanner, Fire GL 3300 GFX card, but the system has an ok driver for that) but other than that all my software has installed and run without major issues.

content: Hard to say since you didn't specify what hardware it's running. If it's older scavenged hardware just to get you internet and program some chips I would use XP. If you're buying legit licenses it'll save you some cash too.On modern hardware that's going to see heavy use go with Win7 x64. It's a really solid OS with a ton of backend improvements over XP and Vista. Using XP on a new machine is dumb unless you have a specific and good reason to do so.Linux only really works if you're comfortable with it and the software you need is Linux compatible. Needing to find crappy hacks and half finished open source projects just to get some work done is annoying and unproductive. Then again if the desired software is available it works great and costs nothing.

content: 64 bit OS'ses are only usefull when you're dealing with huge memory , like for example for databases, hughe photo editing or 3D modelling etcthere is no advantage in using 64bit otherwise and 64bit is in most cases even slower than 32bitIf you're used to windows then use windows a base system , otherwise use a Linux distro - you just want to get work done,I can recommendhttp://www.virtualbox.org/wiki/VirtualBox(it's free) , it allows you to run OS's in a virtual pc, so you can for example run Windows XP in a virtual env on a linux box (or Linux on a windows box).Simply install the OS in the virtual pc, configure it to your liking and then take a backup of the "virtual disk" , if you screw up or have to much stuff installed simply start/restore the backup. I use this extensivly to "test" things out, to avoid a bloothed windows env.note that with windows make sure you configure the env as you want (RAM size and so) before activating to avoid that annoying re-activation based on hardware changesIt's especially good when using different usb to serial drivers who sometimes screw up windows if all installed on the same windows install, just make a separate virtual pc for each env.in theory virtual pc's are a bit slower, in practice - as long as you don't run heavy graphic stuff you don't see the difference, on cpu level the difference is almost zip.

content: Use the PC OS the software recommends you run.If you have a choice between XP, Vista and Win7, choose 7 because its simply an updated Vista with all the annoyances removed. Its also more efficient with memory.If you have a choice between 32 and 64 bit, choose 64 bit; native 64 bit applications do run 2x faster without tweaking, and 64 bit systems can address large blocks of RAM to do large dataset processing.

content: Quote from: saturation on November 11, 2010, 01:53:49 pmsorry, that is not true at all, 64 bit application will NOT run twice as fast . this is a common misunderstandingAssuming the app does not need more than 2 Gb address space (=most common applications), If you install on a certain system a 32bit Operating system and use a 32bit application then this will run just as fast (and maybe even a tiny little bit faster) as the 64 bit version of that application on the 64 bit operating system system. This is true for linux, windows, etc etc32 bit applications on a 64bit windows system take NO advantage of the 64 bit windows os besides a better memory management allowing 32bit apps to use up to 4gb address space (in most cases) .Running 32 bit windows applications (who need less than 2gb address space) on a 64 bitwindowssystem will often be (a bit) slower than running the same 32 bit application on a 32 bit windows.Only when the application actually needs more than (on windows) 3 gb of address space (= not the same as ram) then 64 bit windows is needed (assuming your application is than also a 64 bit application). By default you can go only up to 2b address space on 32bit windows, but you can up this to 3gb in most cases who need this.On linux there is mainly a performance gain by using 64 bit linux and 64 bit applications when your application uses more than 3gb (or 4 - depends on the distro) Gb of address space because the memory management will be simpler, but it will also not run 2 times faster than a 32bit app on a 32bit Linux.bottom line: for apps that do not need several gigabytes of address space 32bit is fine, if you use 64 bit OS then make sure you use also 64bit windows applications for the best result.the only real BIG advantage of using 64 bit OS and applications (!) is that your application can address lot's of GB's of address space . On windows you NEED to use 64 bit for above 3gb (there is one exception - PAE but I wont go into that here) and Linux full 64 bit will be having faster/better memory management above x GB.Edit: above a summary, there is a huge difference between OS's and there is stuff I left out to avoid more confusion and note that address space of a process (!) is the real limit here and this isnotthe same as ram.32bit windowsas a systemcan in general (there are exceptions) not use more than 4Gb of ram, 32 bit Linux can in most cases use more than 4gb of ramIf you need to buy a new windows license then get 64 bit win 7, if you have a 32bit XP license already then this is fine in most cases and buying a 64 bit windows will not bring huge benefits for most tasks.

content: Thanks for your opine, polossatik , but that's my benchmarks for apps I use, twice is typical, its often far more. Anyone can see for themselves and see the differences using available opensource or freeware.Maybe the compile optimization is better on apps I use for 64, I dunno. Maybe such a comparison is different on Linux vs Vista or Win7 multios apps that have varying optimizations, say Firefox. Maybe its wholly per application based. But speed is speed.In my case, I use Vista SP2, as I have 32 and 64 bit versions. For testing, you can use 7.zip which is available free on both 32 and 64 bit and compress something huge that is already heavily compressed so it won't be easy to do and it'll take a lot of time, like a 1GB MKV video file, then use the most CPU intensive mode: ultra. Also, if you have a multithread CPU make sure you use the same number of threads or it will be misleading.You can set the word size on any application to see how it affects speed: 32 bits for 32 bit OS, 64 on 64, then try 32 bit on 64 bit OS etc.,http://www.7-zip.org/Test run 32 bit version on a 64 bit system, then run the 64 bit version on 64 bit OS. Now run the 32 bit version on a 32 bit OS, and compare. Note, you'll have to make corrections for the clock speed and any speed optimizations such as cache's you have on your boxes to normalize the operational times.Note, on RAM usage and Pagefile, choose a test file small enough not to cause pagefile disk swap but big enough to fill physical RAM, as times may seem slower on 32 bit. But, Z.zip will report raw compression times based on CPU times alone, so you can control against the effects of having different caches, RAM, disk speed etc., if per chance its used.Quote from: polossatik on November 11, 2010, 02:31:23 pm

content: cheers,if it's 2 times fast for you, glad to hear it.My main benchmarks are systems like Oracle RDBMS servers , web servers etc (= daily job) and there I can say the difference ofspeed/response of the whole systemismost of the timerather small andsometimeseven in favor of the 32bit env, all depending on the type of load of course. so I'm not saying there ARE no cases when 64 bit is (much) faster.There are exceptions, Java is for example also an env where 64bit givesmost of the timea better application throughput , if you will actually see this for a simple deskop Java app is another thing.And of course with one big limitation for 32bit- scalability (= mainly due the process address size) where 64 bit is really "the way to go"I'll have a look at 7zip and do some tests (but that will be on Linux ), most likely is is due the fact this "extreme" compression must be a heavily memory bound application and the lookup of large compression matrixes or the used register access should be faster under 64 bit .I doubt that when using "normal" compression the difference is that huge, simply because I/O is there a more limiting factor , which will stay the same on 32 and 64 bit (unless you have a crappy driver).But, IMHO, the whole 32bit vs 64 bit is rather academic for most desktop users. I'm not against using 64 bit or so, but it has , on the same hardware,IMHO in general much less impact than people expect.I see no point (unless you need the memory for some applications - applicationsmostdesktop users do not use) to shelf out extra $$ to go to 64bit if you have for example 32bit XP now. You better get a faster disk , better disk controller or upgrade the cpu or so for that $$.with Linux of course you can simply install a 64 bit version, but again, i'm skeptic about that your whole system will be twice as fast.

content: Hi polossatik,Cheers too. I agree 100% with your point of view here. I have the same problem with very large apps that run in 32 bit environments in Win 64 Vista or 7, and yes, the more pure the app is, just running in a 64 bit space, the better off it is. 32 bit runs in emulation in 64 bit Vista, and if there is i/o of any sort, the more intensive it is, the worse the performance is. Some don't work at all. Some large apps, like Peoplesoft, are so legacy heavy, I'd be very scared running that in 64 bit without extensive testing, then again why bother, when you can just get a 32 bit OS and not worry.But for EE purposes with apps that do only mostly disk and net access for i/o, i.e., running Spice, other calculators, and other support software like Openoffice or Micro$oft Office 64 bit, you can get performance gains.Quote from: polossatik on November 11, 2010, 05:02:34 pm

I'm not sure about how tight the integration is between Win7Pro and it's virtual XP machine, but it's really easy to set one up yourself. If that's all you're after, you might be able to save some money.Just wanted to add that in case it mattered to someone. I just recently set up a Virtualbox XP machine on Ubuntu and it was easy peasy so I'd hate to see someone waste the money if they didn't have to.

content: The key problem is while Win7 can run in an old box well with 1-2GB RAM, if you have peripherals in the hardware that are no longer supported you could be in for a wild ride.Thus, If you do upgrade a box OS alone, it may not be worth it, but Win7 is good bet. Better if you get it with a new box.Know there are some very quietly kept interactions with hardware and drivers that can be difficult to diagnose and fix.The most heinous is SYSTEM INTERRUPT based driver issues causing CPU cycles to run high while the machine is doing nothing. This doesn't slow down the machine noticeably because the interrupt can be given low priority when the CPU is given a priority task, but it keeps the CPU running hot because its always running, when you are idle, it will take all the available cycles.You can google it to find more about it.This is often caused by USB, audio card, video driver, disk drive etc., drivers and worse BIOS based issues. Some of those peripherals are built into the Mobo by companies that have been absorbed by bigger ones, or simply no longer exist or not supported, such as Award BIOS, which is now part of Phoenix.

content: Quote from: polossatik on November 11, 2010, 02:31:23 pmEven without the expanded address space, there are advantages to 64-bit. Most significant are the additional registers. Another is that 64-bit integer operations can be done natively in hardware instead of emulation. Granted, you don't see 64-bit integer operations very often, but the few times you do are the times when 64-bit really shines. Back in the days, a 3000+ Athlon 64 and 2.8GHz Pentium 4 were similar performance for 32-bit tasks, but in a 64-bit program like the distributed.net client, the Athlon 64 can be over 3 times as fast.And more applications can use 64-bit addressing than you think - basically anything that needs to work with files above 4GB. It's definitely uncommon in EDA software, but it's something to consider if you do something else like video editing.And note that 4GB and more of RAM is very common now. 64-bit is the way to go for that. And really, why buy a car with a 6 speed transmission and only use 3 of the gears? Using a 64-bit CPU for 32-bit only is the same. You'll be wasting half the logic you paid for. (My ECEN 350 instructor said that 64-bit x86 is a lot "cleaner" in design than 32-bit x86, but I'm not sure how valid that is.)I personally use 64-bit Gentoo. I like being able to customize almost everything.

One way around this was, apparently, to remove the service packs using nLite and then install them seperately after the intallation (though I vaguely remember there being problems with SP3).I had a copy of XP on my old PC, now I have a customized version with updated drivers specifically for my new system, which I created using nLite..o:0|O|0:o.

content: Quote from: shafri on November 15, 2010, 02:11:19 amI think Microsoft's answer is you don't get it - XP that is.XP is no longer offered for sale but if you have Windows 7 Professional or Ultimate, you are allowed to download the license and install XP. This is according to the Microsoft website. The assumption is (I'm guessing) that you already have a copy of XP you can use for this.A quick web search shows that XP is only offered for sale from some of the less reputable online sellers - the ones that sell you 'OEM" software for a few dollarsThe official Microsoft line is that XP is not available for sale any more.

content: Double partition your drive throw Linux on one partition and windows 7 645bit on the other and you will be set. I recommend the Linux partition for running all of the gEDA software.

content: Quote from: NiHaoMike on November 14, 2010, 08:41:23 pmthe only point I was trying to make is that a lot of people think 64 has to be much better than 32 because 64 is a bigger number than 32.It's not, it depends.If you buy a new windows pc with a windows 7 license then of course there are few reasons to install 32bit windows 7 (or XP), 64 bit is then in general the best thing to use.But for example a lot of second hand pc's with "64 bit cpu's" still come with 32bit xp license , in most cases buyingfor thosepc's a 64 bit windows will not make a huge difference. (yes, I know, it will if you use 64bit optimized software or software that uses huge datasets etc etc)If all you do is drive around in town at 50Km/h , where all you need is 3 gears, then if you need to fork out extra $$$ to use all the 6 gears (=buy windows 64) then you're wasting your money and that money is IMHO better invested in a nice sunroofSeen Linux is "free" there of course there is no $$ involved in getting the 64 bit version, so the point is indeed less valid.

content: 64bit windows is... 64bit capabled working operating environment. i mean, it can support softwares with 64bit operation. if you are running 32bit softwares on 64bit windows, then its like giving an old folk with a ferrari. so... its not an OS alone that you should take care, but the whole businessand 64bit operation capabled of calculating greater range of integer/floating values, along with addressing greater range memory/ram location as other mentioned, xp is 3-4GB ram limit coz the 2^32bit = 4294967296 bytes including all those special windows stuffs, with 64bit, the limit will be 2^64 = 18446744073709551616 bytes = 18ExaBytes of ram!. but 64bit will not makes it any faster for the operation, 32bit of a math operation/algorithm will run just the same speed as 64bit version on the same processor clock MIPS. just in case someone misunderstand it that way.so... when will you be needing the more than 3GB of RAM? up to the exa value of calculation? you must be a scientist running a "theory of everything" simulation on your pc or a hollywood 3D Animation reality rendering business or just simply a 3d gaming nuts. running a EE sim and Arduino IDE? win98 can do that easily (well, except the USB compatibilty which is the reason i upgraded to xp). i myself never hit my 3GB RAM limit with all the fancy stuffs that i have. the only reason that people upgrade to win7 i think is because the fancy support, coloring and those special effex things (personal user, not business) and no real commitment to something, no offense, just my thinking from a remote place here.and personally... i really hates win7 start menu, its a backward in term of user friendlyness (menu and sub menu)just my 2cnts.

content: well... the reported increase in efficiency of 64bit is due to some advantage of 64bit, ie for 32bit machine it will/can treat an RGB data in one memory space where as in 64bits we can store 2 pixels of rgb in one memory space and do the operation/compression at once, hence doubling the speed. but its only application specific. AFAIK, compiler based, math, sim, even the 3d game cannot takes advantage of that except rendering rgb to monitor plane. or at least the algorithm is optimized/tuned to take advantage of 64bit, and hence improving the performance, but it will be hardly twice the speed i doubt, and again it depends on what type of application you are running. just dont expect it to be doubled speed for everything. and again you need a 64bit softwares on 64bits OS to take the full advantage.

content: Been using Ubuntu (yes it's free)http://www.ubuntu.com/. Been using it for the past three years and really like it. It was a little bit of a learning curve in the transition but not to horrible. Absolutely love it now. I use the Arduino (ver0021), gEDA, Eagle Cad, open office and i can still run my "windows only" Circuit/Traxmaker 2000 and NI Mutisim 10 under WINE.Also been crash free ever since the change, with windows I was alway fixing virus or had hardware problems, spent more time fixing the bloody computer than using it.
