Ok then, somewhere i saw on my computer that only 64mb of my 9600 was being used and my friend told me it was because of the AGP slot being only 4x and the card 8x. Is there something else i must change for it to use all 128mb or is the card too good for the computer?
First off....your friend is wrong.
2nd, you probably saw 'AGP Aperture' which is different from your video cards memory. The AGP Aperture setting ( in this case is probably the 64mb that you're seeing) refers to the amount of system memory that will be used once the video memory is used up.
