Why is it?, it's how the cards where intended to perform.
Ok, so NVidia designed their cards to auto overclock beacuse it fools people into thinking that they are awesome?
Whereas AMD let the user overclock (if they want to)
at the same clocks, they are the same, essentially
reviews/reviewers dont reflect this

im confused,So what will the REAL 680GTX be called? They gonna make that the new 780GTX? Then call the REAL 780GTX the 785GTX/780TI or something? Im just confused about whats happened to the real big daddy of them all now.
