Disable AGP Aperature in BIOS?

I have come to learn that the AGP Aperature setting in the BIOS controls how much PCI memory it uses for graphics mem space. I am using an ATI Radeon 7500 series PCI graphics card with 64 meg of its own ram. I believe the AGP Aperature is set for 128meg in the BIOS. How is this going to affect performance with my comp as the AGP is not being used?

It won't affect anything.

Since there is no AGP card, the BIOS will not worry about it.

You would be better off gettign AGP, but your not losing any preformance.

Thank you. My compenstein has been acting a little sketchier than usual lately, so I have been looking at anything that may be a cause
