Yes.
Testing at 1080P with a GTX 1080TI is perfectly valid, back in 2012 they used to test at 720P, notice the Crysis 3 CPU test i put up is 720P, but also notice its with Very High "VH" settings, because those guys understand that if you reduce the settings you reduce the work the CPU needs to do.
Today, with cards as powerful as the 1080TI 1080P is the new 720P, but it doesn't really matter, 720P if you like just as long as the Graphics settings are as high as they will go.
Let me say something here.
In the Digital Foundry CPU review the 7600K maxed out at 270 FPS, the Ryzen 1600X at 240 FPS, this while looking at the sky, there are too many who would take an empty scene like that and call it the difference in the true performance of those two CPU's.
I call that completely idiotic. when looking at the jungle, with all the Soft Body Physics, Streamed Shading/Lighting, Long Draw Distance.... the 7600K dropped to 70 FPS, the Ryzen 1600X to 130 FPS, almost double the performance, that to me is the actual difference in performance between these two CPU's, not because the Ryzen CPU is faster 'which to some reviewers would be a very controversial claim to make' but because in that scene the 7600K is working for all its got and its out of CPU, the Ryzen 1600X very probably also it but it is able to perform at almost twice the 7600K's limit, that makes it that much faster.
Its an accurate representation of the comparison.
This does translate to real life gaming, that is a real scene in the game and with my 1070, which as you knowing owning your own is a very high performance GPU... was utterly strangled by my 4.5Ghz Haswell in almost everything, often to the point of stuttering with the GPU down clocking into power saving states it was that strangled and yet the Ryzen CPU i have now, despite the 500Mhz clock deficit allows my GPU to stretch its legs and gaming is now buttery smooth.
That for me was the proof in the pudding.
