from what ive heard on this particular cpu, dont expect much of an
oc from it. i remember there was a guy on here a few months back who
oc'd his 933mhz p3 and got only about 970mhz in the end IIRC.
you might be better off getting another system, because i doubt you will be able to get a big enough difference in performance to see any difference. ( there was a guide i saw somewhere that described how to build a budget system for under $400, if youre interested i can dig it up)
