You have a superb motherboard, first off.
A new CPU would be a cheap upgrade and a lot less hassle.
However, what do you do with your machine? If you're a Photoshop/Premiere guru, then I'd reccomend an upgrade to a new CPU/motherboard.
BTW, a P3 700Mhz (100Mhz bus) FC-PGA would be your best buy.
I'd reccomend buying from compuwiz here on the forums....I think that's his name???!!! Maybe it's Compuwiz1...damn, I forgot. Anyways, his site is
here. He sells CPUs that are guarenteed to work at your OCed speed. The 700Mhz (100Mhz bus) normally have no problems doing 933, but most can get it to 1Ghz+ with ease. Just be sure to NOT skimp on the cooling. No Orbs!
Good luck!
