nope, I doubt it very much.The new GTX 1080 Ti can surely fire up a 3440x1440p monitor no problem. Heck, it can probably even go higher than 100Hz with all of the settings cranked up! Though, that remains to be seen from game to game, but it is pretty interesting what Nvidia has cooked up in just a span of a few years.
Your FOV increases -> more objects, more textures, more shaders -> more then 4K resolution or 1440p. 1070 SLI when scaling well never comes close to 100 fps except maybe games that are rather lightweight.
