Now that RTX 2080 series have hit the market go and just do a simple check on Ebay for the Rx Series, the 570/580 all cost less than 200 dollars and we can build a miner with 1000 dollars or even less if we can wait. That would be a 6 card miner which would give us 180 mhs stable compared to single RTX 2080 ti it is clear who is the winner here.

Not worth to use RTX 2080 series for mining when with that price of a RTX 2080 ti can build a big 6 cards miner now.
