Document: Boot up time is like 7-8 secs now. Unbelievably fast.
Price is good - My total cost for everything was 1399 (laptop) + 220 (above mentioned peripherals). Definitely the cheapest and best performing laptop in its class for USD 1620.4. Update: I installed the mSATA SSD into the Syba adaptor. Removed the 1 GB HDD and installed the SSD. Booted it up. Perfect. Shutdown, reinstalled the HDD into the other SATA slot. Went into bios to disable the 2nd MBR boot. Went into windows, used Samsung Magician software to enable RAPID and best performance on the SSD.
About 4.5hrs of battery life when using only integrated graphics.Sometimes crashes when waking from sleep, very annoying. I've had three of these and they all crash now and then from sleep. Someone on a related model helped out, basically the boot drive has to be in the first SATA bay, not the empty one, please consider if you have put in an SSD. New Video FW must be written as well as drivers stayed on top of, the "optimus" graphic switching is nice but can pose issues.
I bought Samsung Electronics 840 EVO mSATA 0.85-Inch Solid State Drive MZ-MTE250BW and ZTC Sky Board mSATA to USB3.0 SSD Enclosure Adapter Case - Model ZTC-EN002, did a cloning of the windows and opened up the back of the laptop...Kaboomz - no PCIe slots. Just 2 2.5 inch SATA bays. Back to square one... bought this Syba 2.5-Inch SATA to mSATA SSD External USB Storage Device (SD-ADA40077) - hopefully by tomorrow it will be all good.3.
I first bought the version with an extra 8gb. Well the screen had multiple stuck pixels, some how the crystal beneath the screen was damaged in an area. So I returned that version and bought this version and I am happy. The screen is better so far and everything just feels tighter.In terms of the laptop you get a pretty big but good looking (especially for a gaming laptop) machine. It is quite quick in its stock configuration. However, I opted for Windows 7 Pro an additional 16gb Ram DDR3L, blu ray burner, and 480GB M500.The fastest laptop I've used.
Get it, now.I will update this review after a month of use and then a year. If any problems arise I will post it here.
Briefly&#62;First class components.Wonderful matt screen.Rigid chassis, well assembled.Room for expansion &#62; extra drive bay + 3 spare ram slots = max 32 GB.I could rant on, but you get the gist.......Enthusiasts dream machine......Max out all games.......enjoy!
I needed a laptop to replace my Desktop due to space and travel issues,and the need to run games without huge problems. And I can say this has been perfect for my needs. So far its been great if not better than expected with every game I have played so far. Only real downside for me would be the heat that this Laptop creates while gaming and the fans cooling boost sounds like a small airplane while running. I wear a headset so for me its not a problem but for anyone else around you it could be an issue.
You have to go in the is and go through the annoying windows 8.1 interface to get the option to go to the bios. Also no windows install disc. Really MSI?! I had to use a OEM windows 8.1 disc from my cyberpowerpc llaptop. At least they try.
This laptop has really good specs and good reviewsThe problems I faced1. I'm currently overseas and staying at the Navy Gateway in San Diego. This device is unable to connect to the room's public WIFI! Its crazy. My 5 year old macbook and my android galaxy note3 can connect with no issues at all. But when I go to a place with really strong WIFI, there is no issue at all. So maybe I should just blame the accommodation hah.2. Watching youtube videos of GT70 dominator and dominator pro - they all showed that the laptop has 3 PCI-e (mSATA) slots.
Answer: Yes.... BUT you will have to take a few steps:1. Befor you insert the win7 hard drive go into the bios and change the UEFI boot over to LEGACY boot... Save settings then shut down.2. Insert the win7 hard drive and start the computer.3. Go to MSI.com and get all the windows 7 drivers for the MSI GT70 Dominator (NOT MSI GT70 DOMINATOR PRO)4. Install drivers restarting between each driver install.5. After last restart you should be good to go with all devices working properly! Hope I helped...Note: When I first got this computer I did the same thing. But due curiosity I gave win8.1 a try if you have patience with learning your way around a little different version of windows its actually a really good OS so long as you set it to boot to desktop of course :) Not pushing you to try it but just a thought... now Im using win8.1 and its my preference. Enjoy this machine if you get its awesome!
