I've heard that Renesis was very profitable for nvidia, but did not try it Diff is very high now, probably not worth it anymore.
You need the optimized miner to get the best profit..
sp-mod #1 preresults. (0.05BTC +2% fee, pm for details)
The offical miner from a1 does 24.55MHASH on the 1080ti with 100% tdp, and the sp-mod does more than 30 with the same settings and power usage.
gtx:1080ti +22.5% (24.55 --> 30.07)
gtx:1070ti +23.2% (16.95--> 20.88)
What profit you fool, it's not listed on any exchange.
