AGP is better than standard PCI in terms of bandwidth, and for the most part good video cards are found on the AGP bus.
If you are thinking PCI-E vs AGP, than PCI-E is better in terms of bandwidth, but with most times during a transition phase, the PCI-E does not offer a signficant advantage over AGP at the current time. Since no video card uses all the bandwidth AGP currently supplies, let alone PCI-E.
what is PCI Express how do u know if you have that in your computer??? or is it just the Video card???????????????????????????????? please LMK!!! Thanks bye
