You can get 2100+ 1.73GHz AthlonXP's and run them at 2.2-2.5GHz safely, I test them for people and sell them that way they don't need to bother with it. I don't sell them at insane prices either. As for the motherboard, pick up an Epox 8RDA and two sticks (256mb each) of Corsair PC2700 XMS CL2 memory at www.newegg.com For more information on my pretested chips go to "Pre-tested cpus" and click "About pretested cpus". It should tell you what you need to know, if you have any questions feel free to email me.
