Take the 2-minute tour ×  I understand that 64-bit is the best.
However, I've heard that there may be compatibility problem with
32-bit programs. Is this compatibility issue a major enough
issue for me getting a 32-bit OS or is 64-bit Windows Vista
still better, despite the compatibility issue?  I will mostly be
using this for development purposes, but I may sneak in a few
games on the side. :)  share|improve this question Recommend to

programming related questions, but this isn't one of them. –

problem with 64-bit is driver support. Vista 64-bit requires
that all device drivers are signed, so if you can't get signed
device drivers for your peripherals you can't use them in Vista.
