greenbread

also, get the windows 7 release candidate if possible. Much faster overall.GenTom

Windows 7 upgrade came for free with my vista copy so im just waiting till then. Will i notice a fps increase in games like crysis? where every frame counts. also im running crysis on high settings no aa at 1680x1050 and i get around 30-40 fps. does that seem on par for my system?

Faster RAM=Higher CPU temps, for now, I'm happy with my 800.ArchDuke1
