Runs completely fast on my sys @ 2560x1600.

Down to 1 GTX-295 (2-285's on 1 card), other card isn't back from warranty service yet. (was dual GTX-295's).

Win7-64, 24G mem, Xeon 5680, @ 3.33GHz, with Auzentech Hi-Fi (allows me to stream 5.1 audio out my home theater), 4x15K SAS DRIVES in RAID0 for speed. Backed up over Gigabit network to my server with >50T disk space (2-cpu x 4cores ea), 48G, Xeon's X5550 @ 2.67GHz.

Both systems on UPS's.

It's a pain keeping it all running. Honest!
