Wait for Abit NV7m. It uses nForce, which has built in GeForce 2 MX graphics, and this particular board is micro ATX, and to top it off has 3 PCi and 1 AGP.
EDIT: About the MSi KM133A board, it'll probably be fine. I have a KM133, and Savage4 is the best 3D performance wise integrated video before nForce.
