About PCIe (PCI EXPRESS SLOT)

  1. I've seen many graphic cards and motherboards coming out this year. They support PCIe. I heard that PCIe slot is faster than AGP slot.

    There are at least 3 slots of PCIe on many modern motherboards I've seen. (probably 1x,4x, 16x)
    - I'm wondering what devices or hardware would use PCIe slot beside the graphic cards?
    - Why modern motherboards (today) give you 3 or 4 slots of PCIe?
    (Graphic card (single) would only need one slot of it.)
    Sound card/modem/etc still use PCI slot, aren't they?
    - Anyone knows any motherboard that gives you PCIe slots (2 or 3) and also more than 3 PCI slots? (mostly, I found only 3 PCI slots and PCIe slot on many motherboards)

    Thank you for answers...

    My thoughts

    This "new" PCI-E name is very confuseing and hasn't lured me to update my
    Motherboard,cpu and video card yet in order to find out.
    I think it's just a way to sell new motherboards and video cards.
    My 8x AGP 9600 XT will do for now.
    I have yet to see anyone overwelled with their new PCI-X video.
    Lets here from some.:)

    PCIe is faster than AGP. Its also faster that PCI.

    You see PCIe X16 is the replacement for AGP. PCIe X1 is the replacement for PCI.

    However, PCIe X16 has quickly replaced AGP PCI X1 has done a poor job of replacing PCI. Infact there are so few PCIe X1 cards out there.

    On the other hand PCIe X4 is a cheap version of X16. Its usually on cheap motherboards like ASRock America motherboards. But yes PCIe is faster than AGP.
