Devil edition has way better cooler and higher out of the box clocks; 1180 is pretty high for not having to do anything. Devil likely has better power regulation than the turbo duo as well.

If you have graphics overdrive in CCC running at the same time all of these could be conflicting.
I had minor issues with mine until I turned off graphics overdrive and they went away.Just a thought but what are you running for a PSU?
Devil or Toxic are both solid choices.
It's unlikely that you would get 2 bad cards back to back so you should check out other things thoroughly.
If you are using CCC and Overdrive, stop immediately...Nothing but problems, especially if you are using Overdrive plus another utility.
Make sure you have scrubbed all old drivers with Display Driver Uninstaller.
A fresh windows install doesn't hurt sometimes either.
Try removing the card, blowing out the PCIe slot, and reseat the card. A small piece of hair/dust can make things no good; Do the same with your RAM.
Have you tried another PCIe slot?
Check all other cables/connections as well.
If anything is overclocked, return all settings to stock to be certain that isn't conflicting or causing issues as well.
I don't see a PSU in your sig, do you have something halfway decent? Especially considering you're using a power hungry FX-8320. Those things overclocked in the 4.5GHz range need ~200W alone; push them to 5GHz+ and it's more like 300W. It doesn't take much with one of these 270X, as mine is running off a 450W Rosewill Capstone, but a crappy PSU can ruin everything; Capstone are very nice PSU and very reasonable price.
