This right here is AMD's problem. As you stated "Bit if you look at it, it's 98% of the performance of NVidia's top < $1k video cards", is how I see AMD's approach to marketing. When AMD claims that they're competing in the high end GPU market, this is what their logical thinking entertains. They don't seem to realize the rabid nature of the loudest enthusiasts today.
Using the ubiquitous car analogy, if you don't have the absolute fastest car, you're driving a piece of junk.
What amazes me is how the majority swallow this propaganda. That is a very difficult battle to fight.
