Hi and welcome to Geeks to Go. I suggest you check out http://www.powerleap.com/PL-iP3T.jsp
Run the power leap upgrade configurator. I did this for my PIII 450Mhz HP (slot 1 cpu) and found they had an upgrade to 1.2 Ghz. I bought it. I found out about this from a friend that has a Dell 500 Mhz PIII and he had done the same. HP had told me I the max upgrade I could do on my computer was 850 Mhz. It sure works good at 1.2 Ghz!
I have to say the site is not very user friendly, somewhat difficult to navigate. I have run the confugrator on my newer computers and if no upgrade is available, it tells me so. No way to tell until you run the configurator.
