Well my friend, it all depends on whether or not that P3 is a Katmai or a Coppermine and even at that, the P3 would have to be overclocked to a 133MHz FSB to make it 667MHz. The Celeron 600 @ 900 will run circles around the P3 500 (Katmai or Coppermine) assumign its not overclocked....even if the P3 was able to hit 667MHz i dont think its enough to catch up with a Celery @ 900......ask Crashman........overall the Celeron would eb afster, and in other things, there probably equal........but basically theres no point, unless u just wanan do it for fun, than go for it...see which one is faster for YOU.... =)
