It's also supposed to be as fast as gtx980ti sli at that setting. I think we can all say it's bs. Reviews ain't far off so we shall see whats what for real.
Almost certainly, I just live the fact that some people are very picking results from what they want to see.
I think the only semi reliable, leaked benchmark is the 3Dmark showing a stock 1080 is about 40% faster than a stock 980ti, which makes sense from what we know.
