There is good old reliable fallback options such as zec and skien. These have been consistently paying 30-50% more than ETH.
For nvidia cards certainly.
Depends - for the 1070 and 1060, ETH and ZEC (and Skein or Groestl on the 1070) have generally been about the same profitability.
1080 and 1080ti being poor ETH miners do lots better on ZEC Skein and Groestl.
