RX Vega 56 and 64 have been around for a long time now, are there people still building rigs with these graphic cards? Since they are now old AMD cards I expect them to be cheaper right now, also are they still Profitable for a certain algorithm?
If you have low-cost electricity, you can buy these graphics cards. But the price for them is already very high and they have been in mining for a long time.
I agree with the opinion that it is better to look for new video cards
