If you are a miner, then you will receive all the data without translation into Russian. Useless video card, miners won't buy it.
lol eth - 1mhs
Wow... a 5700G iGPU can do that 1Mh for ETH.
There are lots of altcoins these could be used for though.
Question is 2x 6500XT better than a single rx 6600/6600XT for cost/efficiency.
If you want to have some rigs mining altcoins you could have a bunch of these mining various coins for risk/lotto purposes.
Altcoin mining GPU's basically. Not too costly and easy to setup with low power draw.
But for 300$+ as they are currently priced it's better to acquire RX 6600's.
