Why do gamers try as much as possible to avoid graphic cards that have been used for mining before? Is this even making sense because it looks like tech illiteracy to me, does it makes any difference when mining to gaming because my gaming PC is always built ot upgrade with GPU that I have used for mining and there isn't any issue.
I know when I'm building a gaming rig, a lot of effort goes into making sure everything will work together properly and there won't be any bottlenecks for performance. GPUs that have been used for mining have usually been beat to hell, running in hot conditions at max usage with their fans at 100% for sometimes years. No gamer wants to deal with squeaking fans or GPUs that might have issues and damage a PSU...
So I understand completely why gamers wouldn't want a GPU that's been used for mining. I wouldn't either. I've experienced so many different problems with used GPUs... It's definitely a thing.
