Question: Can the processor and video card be upgraded?
Document: It's got a very good video card, the processor can handle pretty much all games out there without trouble, and the screen looks excellent.
The ASUS G51JX-X3 is the best gaming laptop I have had by far. It's probably because of the new updates Intel Core processor cards or because of the new NVIDIA Geforce GTS graphics card. Either way, the gaming is intense and feels realistic. Awesome laptop.
I also have an Acer gaming rig that hasn't had the slightest issue, it's big, well vented and runs like a beast.So while you may not think i'm reviewing this model computer i am, mine just had the older Duo Core processor and the GTX 260 card which on paper is slightly even more powerful than the GTX 360 on paper. After having it(same color, body, everything) i can tell you i don't need to own this one just because it has an I7, because the processor isn't the problem.
ExperienceI have had this laptop for about 5 months. Things to notePros- Fast! Good processor and RAM speeds- Very aesthetically pleasing. Backlit keyboard and screen rules (yes that's a technical term)- The 360m graphics card is very powerful for a mobile mid-price range system- Decent hard drive space however I have heard reports that it has a tendency to fail (however I have not had this problem yet, knock on wood)- Windows 7 64 bit (always a plus)Cons- This thing gets hot!
I Shopped around quite a bit before I bought this model. It runs amazingly, multiple high end games can run at the same time, or you can easily run 20-50 windows of internet explorer without any slow down. I priced other computers with the same specs, they run about 1800-2300 dollars. Forget Alienware, ASUS sells a better product at 1/2 the price. The i5 processor has all the power you'll need for todays applications. The Nvidia 360M graphics card is a leap ahead of the 240M that dell is still fitting alienware laptops with.
100% recommendedGreat design...Battery life like 3 hours in battery saving mode.Battery life like 1.5 hours when playing starcraft 2You can chance performance at any timeI read that the video card is not very good at high resolutions (in games)Speakers are not very good, (low volume)The keyboard is very comfortable...it has backlight B-)I Have not found anything wrong yet
I took me a couple of hours to get rid of all the unnecessary programs, and I did have to install some new drivers for the video card to play Audiosurf, but again, it's no big deal.The back of the screen panel lights up which looks kinda neat, but I don't really care about the looks as much as the performance. The keyboard also lights up with is nice for gaming in the dark. The keyboard is a little bit flimsy which may cause some problems in the future but I don't really think it will.
As stated, some combinations of three keys (like Shift, Z, and X) do not register on this laptop. Not an absolute dealbreaker, but it's something that should be known before you buy. This seems to happen with all Asus laptops, must be the way they wire their keyboards.As for the computer itself, most of the other reviews sum it up well, but my thoughts:+ Screen is beautiful. 1080p gives you a ton of space to work with, approximately twice as much as the standard 1366 x 768 screen on most 15" laptops.+ Great video card for the price.
Do not buy this laptop or any Asus laptop for that matter.I would to remark that before I bought this laptop I respected Asus as high quality manufacturer of high end computer parts. I thought the specs were great and the price competitive. However, since this purchase I have become extremely dissatisfied.Out of box, I had to do a bios update to avoid getting the good ol' blue screen every hour and I had to update my video card driver to play any program that would require something as nice as a GeForce GTS 360M.

They would prefer to do half way fixes on an inferior product and wait till the warranty runs out. If they can't fix the problem properly they ask to "recover the operating system." This means they do a wipe and make you start from scratch.
Answer: Short version: no. The video card in laptops can nearly never be upgraded.  They are pretty much a custom fit.  The processor my be able to be upgraded, but this model had an i7 and I doubt anyone would find much of an improvement with what's available for this socket.  Nevermind, finding a cooling solution for the likely hotter processor in an already very hot, as in sometimes hot to the touch, laptop.
