Combining 3 PCIe cards. 2 in 16X slots and 1 in an 8X slot

Hello,I have no option other than to use 3 Nvidia FX570 cards to drive 5 monitors. Two of them are in 16X PCIe slots with 4 monitors connected to them and one is in an 8X PCIe slot with 1 monitor connected to it. Will this cause the 4 monitors that are connected to the two cards in 16X slots to perform slower due to having one with one monitor in an 8X slot? Or will the monitor connected to the card in the 8X slot just perform slower than the other 4 monitors? Thanks for the help.

  1. I wouldn't worry about it. The x16 or x8 refers to the number of pci lanes available which equates into available bandwidth for the slot. That card is not near fast enough to utilize the bandwidth a x8 slot provides, so there will be no difference between the x16 slots and the x8 slot.
  2. Hello,

    I have the same pretty much the same problem. I'm setting up a Stock Trading Station. I'll be using 6 monitors. My specs will be:

    MSI 890FXA-GD70
    AMD PhenomII 955
    3x 4870 ATI Video Cards
    6 monitors
    1x Blu-Ray player
    1x 200mm Fan
    2x 140mm fans
    1x 120mm fan
    1x Fax modem card

    Which of these will run this set up:
    CORSAIR HX Series CMPSU-750HX 750W, single 60 amp rail
    CORSAIR HX Series CMPSU-850HX 850W, single 70 amp rail

    The 750 watt only has 4x Pcie cables, so I would have to use an adapter, not sure if that would be a good idea.

    or will I need something with more Watts/Amps

    Thanks in Advance
  3. The 750 would have enough power, but since you would have to use the adapter I would recommend the 850. That is a very good power supply.
  4. Thanks Andon48,
    I was kinda leaning that way.
