  1. Yep, your PCI x2/x4 card will work in an 8x or 16x slot.

    No drawbacks, other than the fact you aren't using the slots full potential.
  2. Yes, you can do that. The only draw back is that you no longer have an available PCI-Ex8 slot. Performance-wise, there wouldn't be any difference.

  3. There is a potential drawback on some motherboards .

    Usually the first pci-e x8 slot doesnt have its own bandwidth . It shares that with the x16 slot the graphics card is in .
    So if you use it for anything else it restricts your graphics slightly

    So does it matter if it's also pci x 1 slot card would it still work in those slots to i meant to ask you that?
  5. As long as there is more or equal lanes on the slot than the card, your guaranteed to be fine.
    If there are less lanes on the slot, then you have to start balancing bandwidth of the gens and such.

    Actually found this video the other day, it explains a lot about the PCI.
