That's not true at all. The 460 is the value leader of the Fermi line in performance per dollar and it also runs WAY more thermally efficient than the 470, which by comparison is about the worst at thermal efficiency, running over 10c hotter than it's ATI counterpart the 5850.
It should be an obvious clue that two 460s beating a 480 at $100 less is quite a value.

Add OCing to the equation and it's a no brainer. The 460 leads the Fermi line in value AND thermal efficiency. Reviewers are commonly hitting 850MHz+ core speed without even raising the paltry 40% fan speed or core voltage.
