A couple of items worth noting. The is no option as of yet to go with a
dual Athlon configuration. There are still issues with the 760MP chipset.
Tyan has a beta board ( code name: "Lions" ) but until the chipset issues
are ironed out, it's a moot point.
More points to ponder: Generally speaking, floating point performance is
superior with Athlons.
Also, from a price/performance standpoint, a 1.2 GHz Athlon CPU wholesales
for bout $200.00. Compared this to PIII 1GHz CPU for approx. $480.00 per
Hope this is helpful...
