PCI = one all normal cards use like sound cards, network cards, additional cards.
AGP = Advanced Graphics Port, it was what allowed video cards to have higher transfer rates above what PCI could do so that you could get faster video cards now AGP is hitting its upper limit of what it could do so then comes
PCI Express = PCI express right now is twice the speed of what AGP can do. At the moment you don't need PCI express but thats where all the future cards are going and pretty soon graphics cards will need more then what AGP can give them.
and there is 3 different manuactures and more is because ATI, Nvidia will license there chipset to card manufacturing companies which then they will build there card around the chipset. They can also add features etc to the card. like BFG generally Overclocks the chipsets on the card straight from them so you don't have to play around and do it yourself. some will also put more Video RAM onto the cards to make em faster etc.
