i have crossfire enabled with a 750 corsair HX power supply and an FX 6 core 6300 black edition cpu water cooled to 27c while gaming. now i play bf4 and im not getting any performance gain with 2 gpus while with 1 270, i get the same 60-50 fps on ultra 4 aa and 720p. if anything crossfire performs a little worse than single gpu and the crossfire technology logo on the right top of scream flickers on and off like a bad light bulb and i am using a crossfire bridge and all cables are connected. also ccc 14.4 uses mantle and have too run dx because mantle hiccups my fps. help please ive re installed ccc so many times now and nothing :/
