Well I've researched it and it seems like LESS AGP aperture is better for higher memory video cards. This way the reserved memory isn't wasted because you're not going to be using all 256mb on the GeForce 6800. If you do, you're not likely to be using 256 more... I read on many forums though people telling their "tips" and always mention they have high arpeture for less hitching/faster speeds in games....... So which is it? Personally, I think it's the first from my research. Don't know where people are coming up with this.
