I have the Asus Strix 980Ti DC3 OC and tweaked it a bit more to run around 1400 core clocks. I run the game at 2560*1600, everything ultra and maxed out, Super sampling at 1.5 and I get 60+ FPS everywhere (goes well over 120 fps if I take all limitations off). The only exception is at planetary landings near the surface the FPS drops to 50-60. If I drop the super sampling to 1, its way over 60 even there.
To answer your question will it run Elite in different setups (ultra + max, etc)
a) Three 1080p monitors/projectors: sure
b) One 4K monitos: Yeah, probably only with 1x super sampling tho
