Here's some data from my rig (Equihash):

MSI Aero GeForce GTX 1070 -> 58C  Sol/s: 424.0  Sol/W: 3.82  Avg: 438.5
EVGA Hybrid GTX 1070 -> 34C  Sol/s: 440.3  Sol/W: 3.95  Avg: 436.5
ZOTAC  GeForce GTX 1070 Ti mini -> 48C  Sol/s: 489.3  Sol/W: 3.92  Avg: 489.3

I like the ZOTAC  GeForce GTX 1070 Ti mini for the efficency, but it cost at least 100euro more than the MSI.
