Don't bother with the barton on that motherboard - waste of money. Grab a factory unlocked thoroughbred B that overclocks to 2GHz+ with a decent cooler. You can find these B's in 1700 form (dirt cheap), but if you want to go risk free get one from a site similar to overclockers.co.uk which will guarantee you'll get a factory unlocked B rather than a locked CPU.
With a factory unlocked 1700/1800 XP, you can change the multiplier and run whatever FSB you want. With good RAM and cooling, you should hit at least 150 FSB easily and end up with a 2Ghz+ CPU. Make sure the PSU is up to the task though - I'd say 200W COMBINED minimum allowing a good dose of amps on the 5v rail. 🙂
