P-III 733
I have a processor almost the same, only 733MHz, and it does run well... I can always recommend the P3 PGA Chips
Still useful
I have one of these in my internet connection sharing host PC.
Despite being a bit out of date and below 1GHz, it's still pretty good (running WinXP Pro).
While out of date, if you have one and can use it, make use of it. They're still good for many things.
