Some applications run faster when they are compiled
and run under x86_64. I've seen programs running 30% faster.

On i386, each process is limited to 2G RAM address space.

My own desktop is Fedora 7 x86_64 with 32bit Firefox (to use
plugins that are 32 bits only).

All our 64bit servers run x86_64 Centos 5 or RHEL 5.1.
