Thanks for the link. The reason I'm so skeptical about x64 is that I previously installed it on my BootCamp partition on Mac and when I ran Street Fighter 4 it worked fine on the first launch, but that was it. It wouldn't launch on the 2nd, 3rd and n-th launch anymore. Why oh why?? Also, I've been reading comments about the latest NFS: Shift also not working on Win 7 x64, while it worked for others. I haven't had a chance to try it out yet, because I've replaced x64 with a x32 bit version to test it out anyway. And by the way, Street Fighter 4, for instance, WORKS now on each and every launch. Would NFS: Shift also only work on the 32-bit version? I don't know, but something tells me that that could be the case. Now since I use my BootCamp partition mainly for gaming, is x64 Win 7 really the optimal choice for me? I mean, I really don't feel like dealing with fear of games being incompatible and disappointments upon realizing that certain games apparently INDEED ARE incompatible with the x64 system. What the hell... I thought games were supposed to work on the "oh glorious almighty" x64 system. It really pissed me off. Is there a workaround for such games (other than compatibility mode - which may possibly result in having to switch to like Win '98 and thus getting quite unpleasant gaming experience)?
