PC Hardware have reviewed the Abit KG7 Motherboard and have benched it under both W2K and Linux. here's a snippet:

"Abit also included several advanced memory and chipset timing settings. The memory settings are not very hard to operate considering that there are several templates: Manual, Auto, Normal, Fast, Turbo, Ultra. I couldn't see what settings every template used, but if you know a little bit about clock signals you should be able to achieve the same results using the Manual setting on any mobo."
