I have...
AMD Opteron 165 Dual Core @ 2.62ghz - Scythe Katana 2 cooler
8800 GTS 640MB - stock
Asus MB, Nvidia chipset
2GB RAM
Audigy HD Soundcard
Windows XP SP3
Was really lucky with the CPU, its actually OVERclocked and UNDERvolted. Its at 1.225v, stock setting is 1.8ghz at 1.350
I run the game at 1600x1200 full details with 16x Anisotropic forced on in the driver. Never skips a frame.
But, none of this hardware stops me hitting lamposts or helps me drive better!
