PCIe 3.0 and 2.0 Crossfire 7970s Tags: Asus Graphics Cards Crossfire Motherboards Graphics Last response: November 9, 2013 5:59 PM in Graphics & Displays Share MR2R2M November 9, 2013 5:57:01 PM 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?
