Davegod75 does have a point Gothmoth. If you remember with the KT133 chipset ASUS was the going in favorite because of their success with the KX133, and the KT133 was supposed to be almost the same chipset with only a switch from Slot to Socket. However with the KT133 ASUS lost very early to Abit, who if you remember lost big time with their KX133 MB, and then to MSI. So even though the new KT133A is only supposed to be a change from 100 fsb to 133 fsb the king could easily change.
