I guess it's probably for the price and the overclocking, the Duron will be faster for a lot less. > For what matter though--FreeBSD--Tbird Athlons are faster. That's all that matters since I can't tell the difference for normal day to day operations with Windows between a PII400 and a PIII933. I guess I'm not a gamer.
