The general impression I get is that for the moment it is best to stick with 32-bit since 64 bit can be a bit buggy with software not explicitly coded for it. Is this correct, or is it better to just make the 64 bit jump now? This is going in a new-build system, if that matters, and I have no particular preference either way since I don't use any programs that are really 64-bit optimized.
