Cut-down is relevant because that's why certain people are upset, they aren't just upset because something is expensive, they're upset because of what that certain something is..
If "real" x80 chips were still $500- 600 top-tier consumer GPU's, and Nvidia made Zeus-tier chips for $1500, i doubt anyone would be complaining. Instead, thanks to AMD's blunders, Nvidia have just moved the prices up, massively.
If in some dreamworld Vega curb stomps Nvidias best, and AMD do it for at least 2 generations, then watch chips like the ones in the 1080 go back to where they belong, in the 1060. Prices are like they are because Nvidia can get away with it, simple as that. I agree with buy it or don't, we're stuck with the current landscape. I just don't get why people act like the ones who complain are somehow delusional..
