Not sure how I feel about eth / etc being for gpus. Bitmain has an asic in this algo. Not sure how it compares to gpu.
Tossup to a hair INFERIOR on efficiency at about the same hashrate as a well-tuned 6-card 1070/1070ti rig, perhaps a hair better efficiency than a well-tuned RX 470/480/570/580 based rig.
Lower cost but NO resale value long-term.
