my tests Claymore v14.4
1050 Ti ~ 17.7 strap 5
1060 6Gb ~ 26.5 to 27.6 strap 1 (depends on card)
1070 ~ 33.5 to 34.7 strap 1 (depends on card)
1080 ~ 44.3 strap 2 (without pill)
Great numbers, they're almost on par with their AMD counterparts.
Seeing how Nvidia is better at most other algos, I guess it makes Nvidias more viable than AMD
