Is that really a good idea? A miner's incentive is to overclock the cards and run them as hard as they can before dumping the nearly fried hardware on some unsuspecting sucker. No way to check whether they've been run in reasonable temperature and voltage ranges, and no warranty either. That seems like a gamble, but I suppose that's why they're cheaper.

Definitely planning to see what AMD has coming. I'd like to have the Mac + eGPU option open when my Wintendo kicks the bucket, and AMD are the only ones supporting that right now.

Actually most miners have tried to get the best possible hash per kilowatt ratio out of their cards, which makes sense given that electricity cost is basically the main cost of their business. And the best ratio isn't achieved by overclocking and -volting, but by undervolting and underclocking.

Very constant workload, way below peak capacity - I bet that crypto usage does put much less wear and tear on the chips than heavy gaming use.

Even so, it may be a good idea to take the heatsink off a former GPU mining card, and clean and replace the thermal paste.
Good point, I'm not used to thinking about GPU purchases in terms of electricity cost
