For your Nvidia I recommend not to change work batch from default and use 2 cards in one instance without alternative mine thread. That should give least CPU load and best performance unless you have the "TeamViewer" bug.

Enabling multigpu Without options gives me much better hash rate
conf 2x1060 3gb (non TI) , 19600 sol/s ( about 9800 per card ) but crash randomly. Hope for 0.3v to solve issues.

Very good job.
