The GPUs used for the first two builds (pt.1&2) were all MSI RX480s (~20-21MH/s), I believe the ones hanging here are MSI RX 580s, and the hybrid build was using GTX 1070s.

My commercial operation primarily uses ZOTAC 1070 AMP! Editions.

In my experience, the RX 480s seem to outperform the 580s, but the 1070s are the best middle ground in terms of $ per Megahash.
