Screen turns black after display driver loads, dead card?

While playing a game my screens were suddenly covered in pulsing distortion and random colors. Then everything froze and after several minutes I had to hold the power button to power my machine off. Upon reboot, just before the login screen (when I'm now assuming the display driver would load) the screen would turn completely off and be fully black without putting my monitor asleep. Booting into safe mode and uninstalling display driver with DUU let me get back into the normal os where I used ccleaner to try and clean registry files related to the driver and reinstalled the driver. Again during the install process, my screen turned black at the point when I'm assuming it installed and hooked the display driver. Restarting after waiting several minutes to try and let it fully install the driver gave me the same results as before. No display. At this point I'm either assuming the card is dead or I need to install my OS again. I will be installing windows 8 again shortly after typing this to try and rule that out as an issue but really can't afford to replace my GPU right now and was wondering if there is a way I could prove beyond doubt that my card is garbage or to fix the issue. I have also uninstalled my drivers again and manually went into the registry and deleted all related files and folders to my display driver and used ccleaner again. Same results. I have used restore points before the incident without successes as well. Any help would be greatly appreciated.

CPU: AMD FX 6300 OC'd to 4.6Ghz then to 4Ghz to rule it out as an issue
GPU: AMD R9 270 OC'd to core 1050 (was stable much higher) and mem to 1450 (also stable much higher. My GPU never reaches temp above 76 C
RAM: 8gb corsair vengeance 1866mhz 9-10-9-27 dual channel memory
Mobo: Asus M5a99X EVO 2.0
PSU: Corsair CX750 (yes I know it's overkill, I got it on sale and the less you stress a power supply the longer it should last in theory)

I've already reduced them to stock and past.

Edit: Same problem with fresh OS install. Installing display driver kills the display. I'm just gonna assume I'm right in assuming that the card is dead.
