How much RAM? I believe anything over 3.8Gig is unusable under 32-bit,<br>
and would need 64-bit. I don't know of any other relevant differences,<br>
but I don't run 64-bit anyway :)<br>

And I believe that multiple processes each can use up to 3 gigs each. 64 bit allows a single process to get more than 3Gig, and is a bit more efficient since enabling PAE on a 32 bit proc causes a slight performance hit to all memory access, above or below 4Gig.<br>
