Graphics cards are way more useful for computing than they are for you to play Fall Guys. They are literally designed to compute, and thats exactly what mining is. 

Now, if you have a card being suffocated by 6 other cards and temps are high for a prolonged period of time, yes, components can degrade and lose performance.

Similarly, if you have a card in a crusty ass PC stuffed with dorito powder and cat hair, then youll have the same outcome. 

You can also simply be unlucky and have a faulty card.
