Okay, I am running two HIS 5870 Turbos in crossfire and have been searching through several forums and websites for a few weeks. I have been experiencing serious problems and cannot for the life of me get Crossfire to work with Eyefinity with the graphics cards I have installed. I have heard rumors that these cards in crossfire will not support eyefinity but I feel like there has to be a way. I have resorted to posting this asking for any help I can possibly receive. When I start a game, any game (Skyrim, Bioshock Infinite, Battlefield 4, etc.), my entire computer will lock up and crash at the start screen before the games even begin. What happens is that the middle screen will display the correct image and then my left and right screens will appear as if they have extreme screen tearing or as if a T.V. is not getting reception and then my entire computer will lock up requiring me to hold down my PC's power button and reboot it. But when I disable Crossfire everything works fine. Any help or links to threads solving this issue would be greatly appreciated. Many thanks.
