One good reason for going with 64-bit is the amount of memory the OS will be able to see. I think a 32-bit operating system isn’t able to really use a full 4 GB of RAM — the 64-bit version lets you use probably all the memory you would be able to afford.

So, if you really want twice the memory — maybe you can do it with 64 bit while the 32 bit wouldn’t let you.

There might be some considerations when you are running a lot of 32 bit applications under a 64 bit OS. Maybe someone else can comment on that — but I seem to remember early on that was a bad combination. Something about having to switch the CPU mode back and forth. Certainly all 64 bit processing should be faster.
