+1 Here. Actually, my 5850's are the most stable cards I've owned in many years, and the clock like crazy. This comes from a guy who bought nothing but Nvidia over the last few years.
There is really no reason to overthink this. The 5850 is faster than the 470, less power consumption, and much cooler. Unless you fold, the 5850 is the only logical choice.
