see, to me, a mid-range chip is under 250mm˛, like GTX 660 and HD 7870. All these claims of GTX680 being mid-range do not make sense.
That's because you a priori
exclude the possibilty of GK110's existence/plausibility based on size. If GK110 exists as stated, then it defines what the high end chip is, and GK104 is comfortably midrange in comparison.
