I am on a trip right now so i'll have to keep it short, but 3Dmark numbers of a GeForce GTX 1080 surfaced.
The benchmarks leaked from videocardz, to be mroe specific the results hint at a GTX 1080 running on early drivers which was measured on two PCs. One was run with a Core i7-5820K processor and scored P19005 on 3DMark 11 (performance preset). The second entry was based on a Core i7-3770K processor and reached 8959 points on 3DMark FireStrike Extreme. Such scores if the 1080 are higher opposed to the GTX 980 Ti.
