X64 or X86?

I have just ordered my parts for my new PC and I can't decide whether I want to use X64 or X86. I remember a couple years back, X64 was just asking for trouble since there weren't that many drivers available and there were some issues with running X86 programs.

How many of these issues have been solved since 2006?

Thanks.

Cool, thanks for letting me know. I've done a little more searching and it seems that 64bit is pretty solid now. I think I will go with that. If that doesn't work out, I've still got a pretty monstrous XP system to fall back on for older programs
