I too am on the CS:GO [fuck yourself] bandwagon. Funnily enough, I'd play the game more if not for a rather annoying bug that I run into where the game will suddenly go from humming on my CPU at 50-60% to flooding each core. This wouldn't be a problem...if my framerate didn't go from about 140-150 when vsync is off, to about 3fps. I'm hoping that a side effect of switching to 64-bit might be that this is fixed, but I don't know enough about how that works to be sure.
