I have one Gigabyte 2GB HD 7870 Ghz edition and one Gigabyte 3GB HD 7950 attached to an AsRock z77 extreme 6 MoBo. Will these two cards work in crossfire mode together? I cannot seem to find crossfire settings in AsRock BIOS or Catalyst Control Center which is identifying my second GPU, the 7870, as a disabled secondary adapter while the 7950 is showing as a working primary adapter. MSI Afterburner identified both GPU's and let me tweak each individually but I cannot find any crossfire settings here either. Thanks for any info.
