I have that same setup and I play Crysis, Left for Dead 2, Modern Warfare 2, Half-life 2 ep 1,2, Portal, Far Cry, FEAR, GTA 4 and Fallout 3. All of the games, except GTA 4, play reasonably well at 1024 x 768 or 1280 x 800 if you adjust to medium settings. GTA 4 is strange because you have to almost lower the resolution and settings to the bottom and start tweaking up to get a decent frame rate and graphics. You would be better off playing the game on a PS3 or 360 if you need the best graphics. Otherwise, if you are like me, the graphics do not have to be the best as long as the frame rates are good enough for smooth playing. I do not game a lot, but I like the ability to bootcamp into Windows 7 on the go to play rather than hauling around a PS3.
