Have I mentioned how good this card is,

been hammering it all day and I've come to the conclusions:
Overclocks like a monster, super stable right up to the limit, max O/C being 1401/3800 - This is going to be my 24/7 it could do more but this is tried and tested now.
Kills my CF290X's in everything, 4K games/benching I think it's even quicker than my best MSI 290X O/C in all tests if not it's the same. Completely didn't expect that, thought it'd be -10% when O/C'd.
Now I've sorted my fan profile 1:1 never goes above 65C when gaming so no need to worry about throttling and that's in a NZXT H440 (front cover off). So much cooler again than my CF290X setup which always topped out at 93C and throttled in summer months.
It's so smooth when gaming, no microstutter. Hitting 15/20FPS more in BF games than my old setup 4K.
I'm confident about running Witcher 3 with this card, which was my main reason in buying.
Very happy with this card, it reminds me of the 8800GTX all them years ago, basically it takes care of everything with ease. If you've been reading these pages sat on the fence not knowing what to do, I promised you won't be disappointed if you make the move.
