The concept of the GPU struggling kind of makes me laugh. It's always outputting exactly what it's capable of unless it is restricted by thermals. That would be about the only time it actually "struggles." Ok that and if you have a PSU that's not able to supply enough good clean power.
Anyway at 4K "max settings" may include more AA than is necessary for some players. In some cases one might disable the AA completely. In those cases you can often see above that "magical" 60 fps with 980 Ti SLI. Or you can drop one or two sliders to achieve it.
Perhaps even look at a 4K G-Sync monitor for those games that don't quite achieve 60 but can stay over 40.
