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"

Just checked your post. I think you already found the issue is your GPU. The reason why stress test worked out fine can be the type of stress test you did. Maybe it is a shader issue and your stress test did not touch that part. It depends and usually this kind of issue is not going to be user fixable anyway.
