The noise will not be an issue because it is being water cooled, also the gtx 480's i believe scale better unless someone can prove me wrong (single card 1v1 570 wins though), but the efficiency is correct it is hotter and takes slightly more power, but i can handle it with my system.
Also buying a new 570 with water block would run me 400+ and after i sell the GTX 570 it will only cost me about 300 for a slight upgrade : )
So it seemed more logical to buy the 2 gtx 480s with water blocks than a gtx 570 with a water block.
