It is an interesting fact with the Gtx 1080 ti that some of you may know but some maybe don't.I run one of them and it is said to be doing 45 Mhsh,to me it does near 43 Mhsh in Ethereum mining but once I tried for fun the Ethereum Classic it did exactly 50.9 Mhsh which you can compare it with the Rtx 3060 non LHR,Rx 5700 Xt does just a bit more at 54 Mhsh so the fun fact about this card is that despite being of old generation it is well up to the fight with bigger and newer cards,this I think is the best card Nvidia has produced considering launch time of the card.
https://minerstat.com/dag-size-calculatorThe larger the DAG file size, the lower the hashrate of the Nvidia 1000 series video cards.
At 1070Ti, the decrease in hash rate is not so noticeable.
The gtx 1080 ti is very old and consumes a lot of power. These cards are very hot.
It is very risky to buy them now.
