Question about PCI Express 2.1

I was looking at parts for a new build and I noticed that this HD 6870 said the Bus Standard is PCI Express 2.1

And the MB I was looking at says it only has PCI Express 2.0

Does this mean that the GFX card won't work at all or it'll just work as a 2.0?

Thanks in advanced

  1. It will work fine in the board!
  2. Ok! Many thanks ;)
  3. PCI-E 2.1 is a stepping stone for PCI-E 3.0. But in essence , 2.1 is backwards compatible to 2.0.

    ^^ like rolli59 said, it'll work fine!
