Bruce I returned the same setup back to microcenter. The card was fine but Temps for the cpu was running 90c to 100c while stress testing it and one of the temps monitors alarm was going off. There was also a rattling fan on the cooler. Temps running P3d was around 80c to 95c. Am no computer pro but after a lot of goggleing I learned temps should not be that hi. I got nervous about my 2700 bucks and return it. That's just to much to pay for a rig that is not optimize.
I would get microcenter to check the problems out before the warranty is up.
P3d was running so smooth on the 1080ti.
