I reckon it would be interesting & useful for you to include 4K results in future, but perhaps only for the graphics card that have a chance of handling it, otherwise there's no point in testing them at 4K. And SamB had a good idea there to include sli results, because that's even more relevant for 4K!
At the moment I think 4K is a waste in notebooks for gaming, even with say 980M sli, but over the next 2 generations of mobile hardware I reckon it will become feasible.
