Think mining in general is more stressful then gaming, by that analogy it should game just fine just revert them to original BIOS, also check fans...gamers should be fine
complete opposite. miners tend to undervolt and underclock, not using full potential of card. gamers damage gpus by overvolt and overclocking stressing all the components. if theres a gpu that's more likely to fail, it will be one used by a gamer, not a miner. thats why I love buying gpus used for mining, they've never really been stressed very hard.
I think this depends. Most of the RX gpus were undervolted and they used slightly less than 150 Watts or so.
However back in the Litecoin days most GPUs pulled like 300 Watts or so and were closely kept together since USB risers werent out back then and space was an issue especially with 5+ GPU rigs.
What I found is that most normal gaming never uses 100% GPU usage, so even if the card is overclocked/overvolted it never runs at full capacity anyways. The issue with most gamers is that they have bad cooling because it inside a computer case which is closed and case fans are usually slow and quiet. And if a gamer decides to SLI the rig, its even more strain on the card.
