You might gain some performance by switching to the latest 23.11 drivers; I gained 200+ more points in 3DMark2001 with these. If you encounter problems with them then go back to the 21.85's (on the driver disk). My FSB is clocked at 110 MHz, making my AGP bus speed run at 74 MHz. I think it can do much higher, though. Once you see corrupt textures in games, you know it's running too high.
