GPU performance drops dramatically after Stress-test with Furmark

Hi, im currently running into a problem with my GPU , here's my specs:

- Motherboard: Asrock H81M-G
- CPU: i5 4460 3.2ghz
- RAM: 8GB DDR3 1600Mhz
- GPU: Zotac 1060 3GB mini
- PSU: Corsair VS400
- Drives : 7200RPM HDD and a SSD


My PC has been running perfectly and give very good gaming performance, up until i run a stress test with prime95 and Furmark to check stablility ( i ran them at the same time). It was only 20 mins of stress testing. I monitored the temp very closely, my CPU hit 70*C with 4 core at 100% load, my GPU hit 81*C(with is the temp limit) and throttled it-self to maintain safe temp. The test was completely fine, no shutdown, crash, reboot or strange beep what so ever.
The next day i boot my PC up, i've noticed something wrong with the GPU. The performance drops dramatically, really laggy , shuttering 3D rendering. i have half of the performance in games and benchmarks that i've had before. The GPU doesn't boost it up under load, stuck at 1600Mhz core clock and only 755mV voltage( which should have been 1.050mV) , the Vram usage also wiredly low at 300-600MB.

The rest of my PC performs normally

I've tried to clean install the graphics driver, re-sitting the GPU, power connectors and nothing seems to work.
I checked everthing i could both software and hardware and everything seem to be normal. So is must be the GPU that faulty right ?

Here's pics in Valley Benchmark, the GPU boost up to 1835Mhz for 1 sec and drops to 961Mhz continuously causing the fps to swing up and down as well, it's like a micro freeze every 1 sec
Pls help me out

    Didn't fix it, i think it's a hardware problem, maybe my GPU got faulty after the test, voltage-related
