“On the plus side the prices on high end graphics cards are going to become very affordable.”
best to stick with new ones though ... i’ve read that mining outfits practically burn theirs up by turning up the clock rate as much as possible ... they don’t care if they ruin them because they have to always keep buying the next gen, which produce higher hash rates per amp consumed ...
Yes, you should use a little caution on the used market. The mining drove up the prices on all the cards whether they were used for mining or not. If you are careful you can get a deal now not all were over clocked in fact l’d say most weren’t.
