Wear and tear from intensive use (especially in mining)

A few years ago, cryptocurrency mining became all the rage, and many people bought graphics cards to mine. The GPUs used for this purpose have worked under constant load for months or even yearsBut the crypto craze has subsided considerably, and now many miners have put their graphics card catalogs up for sale. Are they worth it?
