Well at least you could say it potentially helps the environment now that you won't have bunch of gamers crypto mining, or does that not matter the moment there is a drawback that affects us?
I’d argue it’s worse for the environment. These so-called mining cards can’t be used as regular GPUs since they don’t have any outputs - they are compute only. Once they outlive their usefulness they become e-waste since there would be no sustainable secondary market. At least a gaming GPU could be re-sold or otherwise repurposed.
