Well, what i meant to say was, you gotta have at least a Pentium 4 2000, Geforce TI 4600, and two sets of 256 MB RAM wouldn't harm you either. My brother tried to play it with a Pentium 3 700, and a Geforce 3, but he had absolutely no framerates. So he made the upgrade, and now it runs smooth.
Just to make things clear... it's Unreal 2 i'm talking about.
