How much is P104-100 per card these days?
Bitnand.com quoted me $450 per card, which seems like a decent deal for 40MH/s. It does seem like GPU prices have come down a lot in the recent two to three months.
Ebay has GTX 1080tis for under $500 each. That is a terrible deal for a p104. 50mh for 1080ti and ethlargement.
