I just installed another 270x into my wife's pc and everything seems to be working fine, except I can't tell if it's actually running in crossfire mode for WoW. I understand that this game isn't the most crossfire friendly, but I'm trying to at least understand if it's doing anything. Crossfire is showing up in the settings and enabled.
I've got the custom game profile pointed to the .exe(she launches it via the Bnet launcher), it's set to 1v1 and I thought there would be a crossfire logo somewhere on the screen(it's turned on).
System Specs: Intel 3350p, AsRock H77m motherboard, 16gb's pc 1600 DDR3, 750w Psu and WoW is installed to an SSD with dual XfX 270x cards(same model, same bios).
