My neices husband went 64bit and he regretted it after a week. So he went dual Vista's. He says he only uses the 64bit for the few games that will support it. Otherwise it is 32bit for everything else. I haven't noticed any games that support 64 bit but then again I haven't been looking at the specs for them either.

I am hoping the 64 bit will catch on in the next few years. I have seen the power and really liked how fast every worked.
