I'm running a P4 3.2 Gz - 2 gigs ram - Nvidia 8600gt and it runs with everything maxed out with no prob. Average around 30 to 35 FPS in 3d screen. 60 in nav map. Television or Film (I have forgotten which) runs at 30 FPS. The human brain can't really process any faster than around 25 or so. Most of us can't see a studder effect until the rate drops below around 20. Therefore anything higher than 30 is pretty much a waste. Good for bragging rights though!
