You might want to reconsider the Asus board, though. It doesn't offer multiplier control, only FSB.
The MSI K7D Master, however, has all the overclocking goodies and is highly recommended by almost everyone who has used it. It is a great, stable, dual, overclockers board. If you wan to save some cash, get the regular K7D Master. The K7D Master-L comes with LAN and a USB 2.0 card, but costs $40-50 more.
