By the CPU in use? ANY machine in the Intel-compatible category
should happily run i686. An opteron potentially won't run X86_64,
and a recent CoreDuo won't run AMD64.

Depends on what the use case is. Generally 64-bit CPUs
have more registers (makes apps faster) and a wider bus
to memory (faster access to RAM, very good for RDBMS).
On the other hand it may be slightly wasteful on memory
usage, too, since the smallest memory chunk (or at least
that's my understanding of it) is now 4 Byte.
