Not sure if this is the correct area, but the main difference I'm noticing is the video card....
I'm looking for a laptop between 800-1200 that can play most games - Not a desktop replacement, but I travel a lot so I would like to be able to play WoW, SW:ToR or any of my steam games easily. (I'd expect Ultra on WoW which is simple, and decent high on SW/other games.
I found http://www.amazon.com/Sony-BC-16-4-Inch-Headset-Battlef...
which is truly a beast of a computer, but the headset/game make me think "Maybe I could get better...." but I truly can't find much.
The downside of the 540m - a pretty bad card over-all, but it's higher-end processor I think makes up for it.
Which is also a delightful piece of machinery. The 17" screen is nice, although a bit over-kill since I'll be traveling with it. The 560 is very nice, but the processor is less than half the speed of the Vaio. And the display is also only 900 (HD+) not FHD compared to the other.
Any of y'all have any opinions? Or feel free to link a better option laptop. Aiming for the 800-$1200 range. Thanks! (I'd prefer to stay with nVidia in terms of cards, but for a beasty laptop I wouldn't be anti-ATI
