The official system requirements are something along the lines of 3GHz Processor, 2GB RAM, a GeForce 7800 or greater, and 15 gigs of hard drive space. So, let me put it to you this way... I had 15 gigs before I installed it, I still have 5 gigs left, so it really only needs ~10GB... PLUS: my system is running it totally MAXXED OUT! (Keep in mind, my computer runs Pro Street at a 640 resolution with everything off, and looks like S2K's old integrated graphics..)
The graphics in this thing... are NICE!
--EDIT--
Oh yeah, it would help if I told you my system wouldn't it?
AMD Sempron 3400+ 2.0GHz (Socket 754) <-- My Overclock won't work anymore...
80GB HDD
1.25GB RAM (DDR400)
BFG 7600GT (Factory OC)
