I agree with Allen, stick with that list of Motherboard/CPU/Memory combos and you will be very happy. The Asus A7M266 works great and I had that board for a few months, but it only has 2 slots for ram...I switched to the Abit KG7 and it has the same chipset but has 4 slots for Ram making it more expandable,up 4 gigs of PC2100 DDR 266 Ram. Good Luck and I hope this helps...
