I don't think this kind of dick measuring really matters at this point all that much. In terms of power, we have reached a point where adding even more shaders or whatnot doesn't really make or break anything anymore. Imagination and creativity is the bottleneck going forward. Besides, it is very possible that we will see mid-gen upgrade models pop up again, so if you are running after specs, then it's just an unending game of leap frog and the games themselves will turn out to be the deciding factor.
In business, power will always be a factor when considering architecture, technology, etc. That's just the name of the game (I'm reminded of the Empire State Building creators keeping their plans secret from the Chrysler Building Creators).
