Rolled back to 16.7.3 and it's perfect.
Problems I was having is my 290 core clock fluctuates all over the plaec when gaming, playing Shogun 2 yesterday and the clock was dropping to 300mhz at some points causing stuttering so I use gpu tweak to force max clocks, gpu tweak refused to work with the relive drivers and I had two system lock ups.
16.7.3 and gpu tweak from asus is perfect, have a keyboard shortcut for max clocks and desktop clocks.
Have you tried ClockBlocker?
I used it for a bit when my Fury was doing similar a while back.
