I'm thinking of buying a new AMD Athlon Xp 3200 cpu off eBay (can't find it anywhere else). I have two questions. Firstly, how much of an improvement would this make to my system? Secondly, how much is one of these worth? I'm willing to pay up to £80 but if it isn't going to make a difference i won't bother. I mainly want it for overclocking and also my old xp 2500 is acting weird.
