Lol I still want me some 580s graphic cards with 8GB memory, till date people are still buying this gpu for mining ETH and its been like 6 years already that this card have been here, oh I remember 2016/2017 a rx580 was on of the best for crypto mining at the time, anyway I believe something new will come up, its only a matter of time.
I will never buy video cards that old or that inefficient, regardless of the price. RX 5700 / RTX 2070 is the lowest I will go in efficiency.
