I bought a new PC and am rocking the Vista on it.
I’ve also installed WoW, Team Fortress 2, and Portal. I play all of these on high cranked up to 1680×1050. It looks so smooth and awesome.
Dual GeForce 8800 GTS 512s in SLI will do that.
So far I like Vista. I will let you know if that changes.
After I figured out my memory timing and voltages had to be manually set, life was a lot better and Vista stopped crashing. Another huge help was properly seating the heat sink with the right amount of thermal paste.
