I have an MSI ARMOR RX 480 8gb.

I decided to run some stress and benchmark tests,

I ran unigine heaven about 3-4 times and it kept giving me a constant 82 fps with a score of 2100. I was happy, and i moved onto Unigine Superposition and tested it for 4k, and got a score of 3758.
In both these tests, my GPU went to a maximum temperature of around 80 degrees, but never a degree higher. The fan was working at around 85-90% at 100% GPU Load.

My other specs are a Thermaltake 500w TS2 PSU (Its great, regardless what the tier guide says, and its bronze rated, has been working for around an year with no issues), a Pentium G4560 (planning on upgrade, this is temporary) an 8GB Gskill Ripjaws RAM @2400MHz.

After playing CSGO for around an hour, I came back and decided to run the benches/stresses again.
THis is when the **** started happening;

My GPU never went past 65degrees. Wavered at 65-70, but that was the limit. Not even Furmarks stress test sent it past that. Unigines Heaven now gives me an avg fps of around 50. Superposition optimized for 4k gives me a score of 1800 (50% of what I got earlier).

Since the beginning I have been using AMDs wattman for OCing, and even though I did go back to stock settings and reinstalled drivers and sh*t, its still the same. Please help!
