What processor do you have? If you have a Athlon 64 or an Intel 64 bit CPU,
you'd get better performance with the 64-Bit version. The weak side to that,
is even less driver support than what is available right now, which is
limited quite a bit. It is improving every day, though.

Otherwise, use the 32 bit. You can use the 32 bit version on the 64 bit
CPU's as well.
 
It depends on your needs.
I would read this excellent white paper by Windows MVP Charlie Russel - Is
Windows x64 right for me?

Top things to take in consideration, all hardware device drivers must be
64-bit, so make things like your USB Based devices, printers, scanners 64
bit native to work. 16 bit applications do not work either, some
applications utilize a 16 bit installer, so make sure your application is
either full 32 bit or 64-bit.

If you have a 64-bit capable machine and two available partitions, do both.
Otherwise, do x86.
 
Because you need all 64-bit drivers and such I'd suggest just
sticking with 32 bits. The "x64" or "x86" or whatever are needed to
address more than 4 gigabytes .. and they are fairly compatable with the older
32 bit stuff (re-compile required)
I did note HUNDREDS of new IRQs under Vista,
and once IA64 comes out then it is important to switch
(IA 64 defines HUNDREDS of new registers that the various CPU-units
can DIRECTLY OPERATE ON it is an exciting spec at least if you are
into
programming systems and low-level utilities)

Also limitations on FAT or NTFS file sizes are not changed just how much
RAM is directly addressable.

That raises a good question: why will Windows put video, audio, and
networking
all on one IRQ? everything should have its own IRQ its better and faster
this
way.
