PCI-E 2.0 card, possibly 1.0 board

I've got this
motherboard, and I'm looking at some new graphics cards. Specifically the 4650 or 4670 cards.

  1. If your question is "Will a PCIe 2.0 card run in a PCIe 1.0 slot (or the reverse)?", the answer is that it is supposed to run by specification. It should negotiate properly, and the slot or the board should synch down to the 1.0 spec of the other.
  2. You should be all good.

    That is indeed my question. I knew that it was supposed to be all-direction compatible like USB is, the only concern I had is the fact that those cards take all their power from the slot. I thought that PCI-E 2.0 had more power available? And maybe those need it?
  4. PCI-E slots and cards are universally compatable. You should have limited to no bottlenecking issues.
  5. I wasn't worried about bottlenecks. Just worried that the slot might not be able to provide all the power that might be needed for the card. Because those cards don't have a PCI-E power connector.

    There are no worries. None. The spec requires that 2.0 slots and cards be able to work with their 2.0 or 1.1 or 1.0 mates.
  7. Alright then I'm off to newegg. Thanks for the help.
