I just pre-ordered an AIB GTX 1080 from EVGA half an hour ago and this was one of the main reasons why I did it. My R9 295x2 has the power to handle almost any game at 4K (sans VRAM limited ones) but that's only if Crossfire works. With it not working in multiple of the new(ish) games that I am playing and/or want to play I'm just sick of it. Hilbert's review of the GTX 1080 has it at 48 FPS in TW3 @ 4k. Without AA enabled I bet that's close to 60. I'm thinking a single one will give me the FPS I'm looking for. I also will finally be able to play R6 Siege at 4K since CFX is totally nonexistent there.
