  1. Does anybody know if any of the motherboard cmos settings for agp can significantly affect the speed and performance of the attached graphics card?

    I'd like to know EXACTLY what setting you are talking about.. There's a few that might match your description.

    AGP aperture - "Sidebanding" is slow, but if you have a video card with insufficient memory (32mb or less), then you may benefit from setting your AGP aperture to higher numbers.. If I understand this correctly.

    AGP / PCI first boot - Neglegable difference.

    AGP fastwrites - Yes

    AGP 2x / 4x / 8x - Higher the better, and possibly yes.

    AGP time delays - Lower latency = faster

    Video BIOS shadow - On = faster

    There may be other options you can change as well, but I'm sure if properly optimized, you can significantly increase your performance. At the very least, it will show up in benchmarks if you are into that sort of thing.
