Athlon vs Pentium III

I agree with David in general. Asus positioned their A7V as the "best" Athlon motherboard, but it is not
completely stable yet in my opinion. As far as the Thunderbird or not issue goes, I'm pretty sure all they make
now are Thunderbirds -- from 850 MHz and up. As to the performance of the two processors, I did some benchmarking
a while back with an Athlon 850 vs a PIII 850. The Athlon outperformed the pentium in every test except for 3-D
graphics and that is due to the fact the the PIII has a set of special instructions devoted to 3-D graphics which
speed them up as long the developer writes for them. I've attached a .doc with some of the results if you want to
look at them. I'm embarrased to say it's in Word format, but StarOffice will open it.
