I recently bought a 970 (EVGA ACX 2.0 SSC) about a week ago at first, everything was great, then it just started dying on me randomly. The fans would start squeaking REALLY loud and then windows would switch back to the basic color scheme. I didn't think much of it, the card was defective, right? So I returned it and swapped in out for the Gigabyte G1 gaming 970, again at first, it was AWESOME, but then every game just started not being able to be maxed out at 1080p, skyrim, mafia II, Fallout NV, etc. So, I've had 2 different 970's each one has failed me in some way, and this is NOT a driver issue, I've run DDU already (so many times)
