PCIe 3.0 and 2.0 Crossfire 7970s

Hi Guys,

I currently have one HD7970 OC and was looking at the possibility of putting another one in my system. My mobo is an Asus P8Z77-V LX.

Will I be able to x fire two of these cards on that mobo? There is one PCIE 3.0 and one PCIE 2.0. Not sure if that would make a difference?

  1. Its not the fact that one is 2.0 and 3.0, but rather the 2.0 is in X4 mode. You dont want to crossfire or SLI on anything under X8 mode.
