when i had 1.25 gigs of ram, it worked great on 1600 x 1200 and everything on high but textures (medium). With 2 gigs, I've got it all on high with 4x antialiasing. I'm OCing really modestly (315/630). I'm running the 80.40 drivers. Only problem i have is shadows in the wrong place so i turned them off.
