No the point is Fermi just like most high end Video cards is, its an enthusiast's Card. Just like OCing a CPU, if you want to get the best of it, you go water. What they did was prove the potential OC of the 480 GTX, which is very great, and even running at 90 Degrees, it still running at Nv standard.
If you look closely it comes very close to the 5970 in alot of the tests.
Whether ppl like to admit it or not, the card is a powerhouse. It has its draw backs just like any card.
And btw, performance of 2 5850s vs 1 480 isn't the point of most comparisons. Remember the card is exp because its a SINGLE gpu. Which is the price of wanting the strongest single GPU. I know there are ppl that dont like resorting to dual, triple or quad setups.
Anyways that my 2 cents
