A GTX 1080 ti is VERY cost effective on merged folding - probably the best card to use for that - *IF* you have a folding-optimized rig.

On ZEC, they're very close on hash/watt vs ANY member of the GTX 10xx family when all are operated at "most efficient" settings, and they've usually been very close on a "rig-level" basis on hash/$.

THE most cost effective, no - but not all that far off it and some folks are willing to pay a small premium for the higher rig density they offer (and lower time spent managing those rigs on LARGE farms).


The numbers probably vary if you're not in the US - some areas might charge more of a "premium" for the higher-end cards than we usually see here.
