A chat on subreddit /r/pcmasterrace

This, recently I asked if anyone had similar issue I am having, asking why all games I play cause me graphical issues, while all stress tests I did worked flawlessly, I explained everything I did, and I literally got no useful reply's.

Only reply I got was "how old is your GPU" and "did you buy it new or used"

Try the GPU in another rig, if it still has problems then it's the GPU.  Otherwise it would have to be something motherboard related.
