that board takes socket 478 intel chips so the fastest is...the 3.2Ghz extreme edition that goes at 800MHz FSB.

the board specs say it can support 533/400MHz FSB. whould the 800MHz work?

 

how calloused of me....i forgot to notice that....then you're choices are limited to the regular 533 FSB then

it's a 2.8 prescott for $154

 

Although that board supports 533fsb cpus, and the cpu you listed, the 2.8 prescott, is 533fsb, it still won't work on that board. That board does not support prescott cores or celeron d cpus. You'd need to find a northwood core cpu, which is getting difficult. The fastest cpu you can get is a p4 3.06 ghz 533 fsb w HT tech. and a northwood core.

northwoods are difficult to find nowadays though, you might find one in a forum fs/ft thread.

Here's one for sale.

It's oem though, so you'd need a heatsink for it, like the ones listed below it, and you'd need thermal paste, like artic silver 5, if the heatsink doesn't come with any.
