Unless you have more than 4Gb RAM (and many would argue more), you
shouldn't do it. (64bit anything takes more address space and uses more
RAM vs 32bit).
Unless you run a very RAM intensive app or many apps simultaneously,
there is no advantage to running a 64bit OS.
It's the way of the future, but little to gain from it (indeed probably
a penalty), now. (Give it another year or two).
(Admittedly, I'm running Win7 64bit, LOL)
