i have 1gb od DDR 1 memory P4 3.0Ghz 2Mb cache and Nvivia Geforce 6600 le 256mb and the game runs @ 35 fps at all the low settings and still the game looks incredible i'm getting 2Gb of DDR2 ram with a new asus mobo with 1033mhz FSB and a Geforce 8500gt 512mb so i should easely run the game on high settings with 1024x720 resolution and all should be smooth.
