Don't bother with the video CAM linked, only 3 of the 10 laptops listed have useable graphics cards (barely), while the rest have chips that are barely better than integrated (1 of them IS actually IntelHDgfx lol).
This model is much better than any of those:

Basically, at this price bracket ($700-1000), you'll end up getting something with a fast dual core sandy bridge processor (maybe a quad if you're lucky), and most likely an Nvidia GT 540m/AMD 5670/6650/etc. These components are usually powerful enough to max out most games you'll play with low or no anti-aliasing, but at the 1366x768 resolution these machines are most likely to have.
If you want more options I'll look around for more links to good deals.
