As for the HD 4850, it was selling for $129 after the early 2009 price cuts. The HD 7850 is currently selling for as little as $160 with a free game to boot. Even if we ignore the free game, that means the 7850 is delivering FAR more performance per dollar.
A 5850 is at least 50% better than the 4850. The 7850 holds at least the same advantage over the 5850. So you're getting easily over twice as much performance, for less than a quarter more dollars (even if we ignore the free game and, lol, inflation).
You could perhaps have argued that there have been disappointing gains in performance per dollar. But arguing that there have been no gains? That's just not going to work.
As for the 7770, it's true that it is significantly weaker than the 7850. But it's only slightly weaker than the GTX 650 Ti which costs significantly more (closer to the 7850 than the 7770, even though its performance is closer to the latter). And to top if off, the 650 Ti is the memory bandwidth-starved card, not the 7770 (at least to a lesser degree). The 650 Ti has a significantly more powerful GPU, but only 86 GB/s memory bandwidth to the 7770's 72 GB/s.
