Has anybody tested the M20-45 with 8NM Samsung chips? I am very interested in this gear.

Seams is the best choice at the moment. But price is very high and delivery is in December. Maybe I become 0.5 BTC in December for 2000 USD. I have this time the same feeling as in November 2017. Bitmain sells the s9 for high price with delivery in late February.
