I just finished the rig in my sig and installed vista 64. Loaded up Crysis and wow big big difference from my athlon 3200 and 7900gt! I was barely able to run at medium settings in the demo with my old system. The new system has most of the settings on very high and just a couple on high or medium. I figured it would be a noticeable difference but this is really big. The system is also almost silent with the vf900 on the video card. Anyone suggest a good keyboard and mouse for gaming?
