It's getting very marginal at best - I just realised a couple of nights back I didn't have ant of my rigs with 2GB cards back online yet - turns out my pair of 2GB HD 7870s can still run ETH but they're 60-80% more profitable on ZEC right now, so I'll probably just leave them pointed that way even when the profitability drops back to parity ballpark.
 Moving over to ETC might also be an option, it's generally very close on profitability to ETH.


 For comparison - Genoil 1.1.13 on my 1070 rigs with Afterburner set for +550 memory, -200 core, 75% power limit pull 28-29 Mh/s under Windows 7 with the 372.70 drivers. I've had nothing but ISSUES out of any of the 375 series, and NVidia has stated in at least one of their "known issues" on one of the 375 series drivers that they had problems with Folding@home - I suspect that issue likely ALSO affects mining.
