Second, supporting graphics card [SOLVED]

[shoutingsteve]

Despite crawling the internet for nearly three days, I have yet to find an answer.  I apologize if this has already been discussed (I searched this forum several times and was surprised that I couldn't find the answer)

I have two cards, a GTX 1070 and a GTX 750.  I have them both installed and am using three monitors.  The first (set as my primary display in the Nvidia Control Panel) is connected to the GTX 1070.  My other two monitors are connected through the GTX 750 card.  Everything is showing up fine, and the same driver is being used for both cards.  They are not connected through an SLI bridge and I know that they cannot work in SLI, but both are driven by the same driver version.

The question is: Is each card doing the work for only the monitors connected to it, or is the 1070 doing all the processing and the 750 is acting as nothing more than a connector to plug in the other monitors?

Since you have set your GTX 1070 as your primary GPU, all the computation and rendering is handled by the GTX 1070. The GTX 750 in your system essentially served as a display adapter to be connected to.

Unless you manually set an application or assign a function (PhysX) to run on a specific GPU, it will mostly use the GTX 1070.

I expect the answer is no, but is there a way to set the rig to push the graphics for other two monitors through the other card?  The most intense thing I ever do on those screens is youtube and minesweeper.

not efficeiently

 would be easier to setup a satellite system (small adjacent rig) and use a mouse/KB sharing program to make connecting the rigs together

I did a little testing.  I tried three different GPU benchmarks and have found that putting all of the monitors onto a single card resulted in better performance. (plus it's one less fan going around in my case, so it's quieter)
