BX mainboards for 133mhz systems
Anandtech has a great article about using 440BX mainboards for 133mhz clocked systems.

He has some great info in this article, one tidbit of which is that Asus and other 440BX mainboards since the P2B automatically select a 1/4 PCI multiplier at 133mhz even if it isn't a selection on the board. VERY interesting.
Since the AGP multiplier can't be changed there were some tests of how stable the major graphics cards are when overclocked to 88mhz. As far as the Matrox cards go the "normal" G400's worked at up to and including 133mhz on their test system, which used an AOpen AX6BC Pro. He also noted that the G400Max and G200 sucessfully worked at up to 148mhz.
Toms Hardware has also used the 440BX very sucessfully at 133mhz. In fact one of these with 133mhz memory bested by a large margin the performance of a dual channel RAMBUS setup. It's also a ton cheaper.
