There aren't too many super-7 boards that had their chipsets and designs updated to have halfway current features, the important ones being strong CPU and AGP power feed, UDMA66 IDE, hardware monitoring, and large cache.
Both ALi and VIA have updated their south bridges to be UDMA66 capable, and VIA's MVP3 chipset can drive 2 MB of cache.
ASUS hasn't revised the P5A to use the UDMA66 capable chipset, Gigabyte did so with their 5AA and 5AX. Yet they both have 512 KB of cache only.
Epox, Tyan and DFI have offerings with the above features, all are built on the VIA chipset, and are ATX form factor ... for BAT, DFI has the only one, K6BV3+/66.
The DFI boards come at very decent prices, yet their ATX board has only four PCI slots. Epox and Tyan 2MB boards are a bit pricey.
