dude, i have a gig of hyperx, 3.4 P4, Asus P5AD2 Premium and a 6800 256meg pci express and i can max out everything with Antialiasing turned off at 1024x768, the only issue is quiting out of the game which mya take up to a minute to resume normal function after hitting quit, should you get another gig you will have no such issue. You turn it on low and u watch the frames go by in excess, i pull 50-60 fps in this config so you shouldn't have any trouble.
