Our sister company, ThinkAV, has been able to secure a monthly allocation for ASUS RX580 DUAL 8GB video cards.  These video cards have an excellent Hash/Watt rating, while reaching 30MH/s on ETH, 980 H/s on Cryptonight, with temps hovering around 66 deg.

As GPUs are currently hard to find, there is a 4-week lead time on these cards.
