Generally the GTX480 is on par with the GTX570, it is slightly quicker clock for clock but the GTX570 can reach faster absolute clocks. At higher resolutions the 480 pulls ahead slightly due to its larger VRAM.
Something to note is all the commotion that about the 570 frying its VRM's with significant voltage increases. While there are ways around the heat and noise of the 480 there are no walkarounds for the VRM issues.
All said, I think that the 570 is the better buy if they are the same price, but if you can get a 480 for cheaper it would not be any lesser of a choice.
It's not just significant voltage increases that lend to the failing of the VRMs. It's people who think turning off OCP will allow for higher clocks. Which is not always true.
So they turn off OCP and update the bios to allow for 1.2v, then things go BOOM!
Also OP keep in mind that 850 core brings the 570 into 580 territory, save for the extra ROP's and CUDA cores.
I have mine overclocked to 850 and the temperature never exceeds 50C delta. Meaning that my ambient temp in the basement is 15*C and the card doesn't go over 65*C at those overclocks with the fan profile set to 1% fan speed for every degree Celsius that the core puts out.
Overall it's an excellent card. I give it my approval. Going from a 6870 overclocked to 975mhz I still saw significant gains from switching to this card.
