Return the CPU you just bought, if the place you bought it from will allow you to do that. Yes the 939 is an AMD socket and the processors available for that socket will outperform the P4 you have. Well, What do you use this computer for anyhow?
i hope! i've been using intel based processors since the 200mhz series!!
Well, thank you so much!!
you really were a big help!
now i just need to return the p4 3.0E processor i got!!!
