My friend is going to be grabbing the 1080 Ti for mining with NiceHash, but I was under the impression that the GDDR5X ram isn't that great for mining.  Would the 1070 be a better option?  A 1070 can be had for around $400.  1080 Ti is about $760.  He doesn't pay anything for power, so just purely accounting for hash power per dollar spent, what's the best option?

Also, is NiceHash a good solution for him or would you guys recommend any alternatives?  What has been your personal experience with it?  Any help or information is appreciated.
