If you want a KT133A I think the best to OC are Asus A7V133, Abit KT7A Raid or non raid, also the epox, and the best the Iwill kk266.
Im about to get one of those mobos too, but im gonna wait till Athlon4 comes out, and see if the DDR memory goes down, also the DDR mobos go down a little bit. And wait to see if the DDR will make a big difference, then get a DDR mobo or one of those mobos.
BTW Biggs, IWill KK266-R is very attractive!!! I can see my name written all over this mobo!!! LOL But i will wait a little bit more!
