Can you still build mining rigs with 6gb GPUs like gtx 1660s in 2022? For how long can this graphic cards keep up with mining? I'm sure they are better option over rx580 4gb, what do you think?
rx580 4gb is no longer on sale in stores.
The gtx 1660s is a good graphics card for mining, but it will lag behind modern graphics cards.
Calculate the purchase of one RTX 3060 / RTX 3060ti video card instead of two gtx 1660s video cards.
If you have expensive electricity, then you will have high costs after you finish mining Ethereum.
