You can also try to dual mine ETC+ZIL and the reason I say ETC instead of ETH is because the card GTX 1080 ti can do almost 10 Mhsh more in Ethereum Classic than it can do in Ethereum.Also RVN is a very good coin to mine as this card does easily 25 Mhsh there,you have a lot of options with this card,it remains still strong and relevant in mining during nowadays although it is an old production.
