Assuming you chose your mbox format and other software intelligently,
the fundamental bottleneck tends to be disk access & write. Having
your disk behind something like a NVRAM caching RAID controller or
maybe a logging/journalling filesystem utilizing a fast non-volatile
logging media is likely to make a much bigger difference than the CPU.
Network bandwidth may also be an issue for some configurations.
As for the Athlon, its a good processor... but obsolete in form which
it was mentioned in. It makes *very* little difference in real terms
on a mail system.
