Everyone keeps pointing at Nvidia, yes you are right but there are some AMD cards that are way cooler than you expected too, for example the RX5500 and RX5600, if you don't try them you won't know,they are extremely cold
RX5600 has long been out of store, and in the secondary market their price reaches 800-850 dollars due to the limited supply. These video cards are probably the best ones for mining Ethereum, but they will lose to Nvidia video cards in mining other coins. But for those people who bought these video cards in 2020 or earlier, this does not matter, because they have paid back their investment several times.
