Well, you could install an XP3200+, but it would be running much slower than it's designed to. The fastest proccessor designed to run at 266 FSB was the XP 2400+. Personally, I'd get a 2500 and throttle it back to work with your board, then when you get a newer board, bump it up to 3000/3200+ speeds. Some people here will reccomend this with a 1700+ also, but if you do that make sure you buy a tested chip that's proven capable of those speeds.
