Hi, I'm probably gonna be getting some new HW for Xmas, so I was thinking a good gaming mouse and a new keyboard and maybe another 2gigs, any suggestions? I was wondering will I notice the difference with another 2gigs? (Vista 64bit) I play quite a few games, although I haven't tried Crysis yet. Is it true the demo is DX9 and is only single threaded, if so, the real game should be easier to run, no? Does anyone really notice the difference between DX9 and 10?
