In Russia, the seller asks for $ 540 for a used Vega 56 video card produced in 2017.
This is the first problem. And the second problem is that these video cards were bought mainly by miners.
Gamers passed by these graphics cards.
Therefore, I prefer not to buy these graphics cards.
No no no, don't get it wrong, you can do research on your own using google, RX vega 56 is indeed very good for mining Ethereum, it can produce up to 52megahash per second, presently you can get one at 460$ on ebay, I believe that's still a fair price, it's not about been old or not, it's about profit making
