It would run it but bad fps, even 2x sli will be pushing it. It's 11 million pixels roughly vs 8 million pixels for 4K vs 6 million pixels on a 1080P surround setup. I think one 980 ti with 1080p surround only pushes maybe 60 fps but not fully maxed on every game and 2 x sli 980 ti's push close to 60 fps fully maxed at 4K but that would be another 30% of resolution.
2x sli would probably be in the 40fps range fully maxed out settings, if I had to guess.
