I'm specing out a new web server, and want to be able to compare an

find "server" quality boards for the P4, but I can't find any info for
Athlon server boards (except the Tyan Thunder K7X Pro, but I don't need
dual processor and it's twice the price of the Intel S875WP1-E that's
being quoted for the Intel-based system).


If you need server purposes, I'd highly highly highly recommend going
with a dual processor setup. You can always run a single cpu and upgrade
to 2 later when you need better performance. For server purposes, the
AMD 64 Opteron blows any Xeon away. It's actually not even close.
