Seems that way, the blockchain driver isn't that great for gaming though so you will lose out there, but it doesn't take that long to switch drivers, just enough time to get a cold beer before an hour or two gaming...
The key take away here is that it is quite fast mining at -30% clocks and a tiny boost to memory, and -30% power limit. You have to tweak the fan speeds to make it stay under 70c (around 2500rpm does it) otherwise, as soon as 70c is breached, the hash rate drops to less than 35, it is very odd, but something happens at 70c
Wish I had the water cooled one now as it would be silent whilst mining at low temps...
