I too had this same error with my rig. I re-installed clean drivers and even RMA'd my GPU with EVGA. But this did not solve it...
Using EVGA Precision X, I noticed a spike in GPU activity before the crash, when the temp of the card reached 77 degrees, . So I made a custom fan profile using Precision X, so that when temperatures reached 75 degrees, the fan speed increased dramatically to keep temps below 75.
This has FIXED the problem and I haven't had a driver crash since. I dont know why the card spazzed out when it reached 77 degrees... seems a pretty average temp to me. But i guess the card will also last longer keeping it well below 80!
