My motherboard has PCIE 1.0 and My video Card Is PCIE 2.1..? HElp?

Ok as i described in the question above my M/B has PCIE or 1.0 and My video card is PCIE 2.1, does this affect the performance of the video Card, i mean in terms of gaming, some says that the video card will not perform to it's full potential, it will slow down.. Will it..?
Does the video card 2.1 give full speed if it's placed at PCIE slot, in terms of Gaming...?

  1. Well, there aren't actually 2.1 slots manufactured, and won't be,only PCI-E 2.0 slots. PCI-E 2.1 GPU's are made to be compatible with all the new features PCI-E 3.0 Interface, as long as your graphics card is running, there shouldn't be any slowdown caused by the Bus interface.
  2. Some people have had issues with a 2.1 card in a 1.0 slot.

    See this:
  3. Yes, that is due to older boards not getting a BIOS update to support the cards, but his card seems to be working fine, he just thought it would perform better from dropping it in a PCI-E 2.0 slot.
  4. There's a few technical differences between a PCI-e 2.0 and PCI-e 2.1 card, but a PCI-e 2.1 card is not "faster" than a PCI-e 2.0 card. Which PCI-e 2.1 card so you have?

    Basically the difference between PCI-e 1.x and PCI-e 2.x is the bandwidth. The newer standard has twice the bandwidth of the older standard. Unless you have a really, really powerful card, the PCI-e 1.x slot should have enough bandwidth.

    I have a Radeon HD 5850 PCI-e 2.0 card in a PCI-e 1.0 slot and it runs fine.
  5. I have Radeon HD 5570...

    a 5570 will not saturate the bandwidth of even a pcie 2x slot. Your performance will be fine. Im currently running a 2.1 card (6850) in a 1.0 slot and it runs great.
  7. Ok thanks all for your help, i din't had any problems with the card, the only problem was the screen flickering, after changing the PSU that also got solved...
