AGP & PCI

I'm confused about the AGP & PCI.
How do I know which I have and what bandwidth I have for them?
I'm relatively new to this but I know a little.

  1. Easiest way to see which one you have is to take a look at your motherboard.
  2. Or download CPU-Z.
  3. Nice pic ;-)
  4. Thanks, this is very useful!
    Would you have AGP as your main and some other PCI; Google says they might be 'extension' or 'expansion' slots, what are these?
    Thanks

    I have got CPU-Z but I'm not sure where it says?
  6. older boards had a single AGP as their primary and a few PCI slots to support other expansion cards, more recent boards tend to have one or more PCI-E slots.

    They are called expansion slots because they allow you to plug cards into your system to expand its capabilities over those which the motherboard provides.
  7. agp uses the ram on the mother board pci-e uses the ram on the video card

    Click on "Mainboard" and look down in the "Graphic Interface" - your bus type and transfer rate are written there.
    There is an example in this site: http://www.softpedia.com/reviews/windows/Cpu-Z-Review-38137.shtml
    look down at the middle review image (example of AGP X8 interface).
  9. Need to know what kind of slot you have first before we can suggest a card. But at that price that card is a pretty bad buy, overclockers.co.uk has an XFX 5750 for the same price.

    So why do AGP cards have onboard memory then?
