Good for you. I have god awful luck with AMD cards so I would have ended up with one that black screened as soon as you touch the mem frequency

hence going for the Sapphire. Plus I prefer the look of the Sapphire but they're both great cards.
It could be anything really. I've tried loads of things and to be honest it's probably some issue with something in the way I run games (i.e. 120 Hz etc etc) and Mantle and the drivers and the game.
I say this because 14.7 first driver was god awful. Would be lucky to make it 30 mins without crashing in BF4. With the RC3 one things improved dramatically but still not perfect so it's obviously something to do with the drivers even if not the drivers exclusively.
