Think about it, you need around a 20-25% performance increase over 5870 to match/beat GTX480 in most situations. Cayman needs a 10-20% increase over that to match/beat a 512SP GF100, if it stays around 700-750mhz.
How would 6% increase in shaders get nVidia 10-20% performance with a full GF100?

I'd say 30% over 5870 is enough to match a full GTX480.
