I have a AMD64 2800+ processor, nVidia 6800 GT GDDR3 256MB AGP GPU, ASUS K8V-SE motherboard, Sound Blaster Audigy 2 ZS sound card, Two Western Digital 34.7 GB 10,000 RPM SATA hard drives. It runs great! There is a little lag, but overall it's good. The load times are seamless for indoors, and outdoors its like 5-6 seconds. Not too shabby at all!
