The ATI Radeon 9700 is capable of running at AGP8x. I'm currently running the Radeon 9700 on an Asus P4T533 mobo, which only supports AGP4x. This means I'm getting 1.06GB/sec maximum bandwidth to the North Bridge, which in turn has a maximum 4.2GB/sec bandwidth to my RIMM4200 memory. If instead, I chose a mobo that supported AGP8x and DDR400, then I would be getting a maximum bandwidth of 2.1GB/sec to the North Bridge, which would in turn connect to DDR400 SDRAM with a maximum bandwidth of 3.2GB/sec. Would my video card benchmark performance improve if I chose a mobo that supports AGP8x and DDR400?
