Also disabled ULPS in registry (won't auto switch).
At 100% GPU use, temp topped out at 53c at 50% fan speed. played Dead Island without issue and Batman Arkham City without issue.
I have to use both programs together to get this working, otherwise it seems the card drops to 300/150 gpu/ram which I think is part of the problem as it kept dropping to these every 5 seconds even under 100% load, although I can't be certain seeing as also I upped the voltage in 2d so even if core speed drops the voltage doesn't. This I believe is what was causing the crashing. This doesn't happen using the above combo for some reason, as I tried both CCC and AB on their own and couldn't replicate the stability.
Now if only it all just worked out of the box...
