Dude it's really not worth it. The performance gain will slightly be noticeable, but not much. For that price you can get a duron and then all you have to worry about is getting a motherboard and some ram (I figure you have an LX based board with EDO ram possibly?) I think that if you don't have the money for that right now, you should wait a bit and save up, because I personally feel that buying a P2 is a big waste of money, unless you can get that 333 for dirt cheap (which should be the case, but you'd be surprised).
