I found that 3DMark outputs the tests to current desktop resolution settings (internal scalar?) so it makes for a good test. A comparison of desktop set to 60Hz vs 45Hz.

The cap seems to be 77fps in the games/apps I have tested so it's possible it has been there since I got the 4K screen in December. Only really noticed it because it seemingly causes a performance hit close ish to the cap.

That seems like a different problem. You should report that to NVIDIA because you shouldn't have to do anything special for SLI to work properly at higher pixel clocks with the GTX 970.
