I feel like it's BS since they are showing actual benchmark results. Also the results are super outdated considering how much stronger the 680 is than the 7970. 7970 is only 1% weaker than a 680. But the actual number of cores etc, I think is true.
It's already been confirmed that the Titan is a completely separate chip from the GTX series - that's the first flaw I found, and it took all of four seconds to notice.
This isn't reputable.
All is faked, the Team Green fan fair is running wild, The GTX780 is a step up on the 680 but nowhere near a GTX 690, but still under NDA so thats about that
