as for a visual representation of these three ports, see below:
first is PCI
Second is AGP(burgundy/brown)
Third is PCI-Ex16(orange)
you need to open your computer and look for which one you have, You will most certainly see a PCI port but this doesnt necessarily mean that you need a PCI card.
as for installation, you need to choose a card carefully as some cards are too big for standard ATX cases, but for actually installing the card, just slot it in and plug in the PCI-E power connector/s to the card and your away.
ive also included a picture of my interior to show you whereabpouts the Graphics card should be situated, its the big green long card.
