Firstly try 14.6/14.7, if no luck:
did you do a fresh install of windows or just removed drivers and installed new ones?
I'd be thinking of doing a fresh install just to rule out drivers.
Im running 14.4. Im getting problems with videos just been a green screen, the audio can be heard. Its happens on facebook and on iplayer, however youtube seems ok. Is this a driver issue or do I need to look elsewhere? Was fine on my previous GTX670
Sounds like a flash player issue. Which browser? Try fiddling with hardware acceleration settings, or using Chrome/IE.
Any-one have a memory leak fix for crossfire uses since the 08/07/14 bf4 patch? Other than turning off mantle or crossfire of course?
Really annoying starting out at 120FPS and dropping down to 50 after 20mins of gameplay.
