The best board for the job is most likely the Asus A7V133. You can get it either in the RAID flavor or ATA100 non-RAID. It's super-stable, even if you overclock it. Also, as far as the PC133 - DDR issue goes, here's the simple facts: PC133 is very fast, especially with CAS2 and your 1.13GHz Tbird. If you're one of those people who desperately want a zillion frames per second in Quake, DDR will be fast enough to make your skills look shameful. But the catch is that DDR is also insanely expensive. Not only do you have to pay through the nose for the RAM, the boards that support it are also much more expensive. It's a trade-off: Fast RAM for a good price, or super-fast RAM that requires twice the price for the components...and a performance difference noticeable only when you really tax the system. IMHO, get the Asus board with 256MB of PC133 CAS2.
