Please note the "I have a chance" line - I have some discounts that I
can apply against Intel 830D's which would take the overall cost down
to less than an Opteron machine - and I'd be getting dual-core for
that lower price as well.
Pentium 4 830D's have EM64T support; it's not just Xeons.

You can compare anything you want. It's a comparison for that reason.
My two options are an 830D or an Opteron-based system. The main
question is 64-bit support using Debian-amd64/kernel 2.6.x. Is it any
different than installing Debian-amd64 on an Opteron box? I already
run it on 7 Opteron-based systems and an Athlon64 system.

little slower than AMD64. However, maybe that's just a bottleneck that
will be fixed soon, much like when Hyperthreading came out?
