Let me comment that my 64-bit commentary about I/O is based on  
experience with Opterons, which have excellent I/O bandwidth.  The  
Intel EM64T boxes do ok, too, but I have no experience with other 64- 
bit CPUs.  The opterons are just a notch above anything else that  
I've used.

That said, I run 64-bit FreeBSD on all servers capable of it, just to  
have consistent system images (all my new boxes going forward are 64  
bit, so I can eventually phase out the 32-bit system images).   
Management of multiple systems changes the decision making process  
sometimes...
