I never had SLI 780s, but I had SLI 980s, and the 1080 comes very close to the performance of SLI 980s, or passes it in games with poor scaling I don't have any direct benchmarks between to two setups, but one thing you might have already found as one of the implied results, is comparing things like 3Dmark scores, and factor in that benchmarks will have some of the best SLI scaling, so those benchmarks tip in the favor of the SLI 780s, compared to a single 1080 that doesn't have to deal with SLI scaling.
another thing to consider is the 2GB of vram on the 780s, that could be a limiting factor at some point.
Though the best way to get results is to look up gtx 1080 performance, and run the SLI 780 test yourself, as finding benchmarks for the 780 SLI for modern games and drivers may be hard, but the 1080 results will be ample.
the big question of course is how much will (if at all) your CPU might affect results, given that you have I think a x79 CPU and most benchmark results for 1080 will be using something newer I think.
