If you read this thread the comparison was fairly made to $440-450 GTX580 versions not > $500 ones. But as I said 1.5GB --> 3GB actually mattered. 3GB --> 6GB makes no tangible difference.
AMD has been very careful with their words here, but the gist of matters is that the 7900 series will remain the mainstay of AMD’s enthusiast product line until the end of 2013.

Sounds like AMD will launch some HD7000 desktop cards, like lower end 384 SP ones or close some gaps in the line-up between 7770 and 7970GE. It seems almost certain there that HD7970GE will remain the fastest single AMD desktop chip until the end of the year.
HD7970 OC. Outperformed the 580 > 35%,
paid for itself. The only time in GPU history.
No one is making a claim that high end cards should have amazing price/performance. It's understood that they don't. Again, I think you didn't read the thread in detail to get the context.
If the Titan is viewed as a limited edition card, $900, $1000, $1,500, $2,000 are all justified. If the Titan is viewed as a GTX580's real replacement, its $900 price is laughable because that essentially means NV is establishing new price levels of $500 for mid-range chips like GK104/GM104 and $900-$1000 for flagships. See my point now?
