Damnit, just lost the pic, but Chiphell had a 6870 vs. a GTX 460 1GB and the 6870 scored on Vantage H11xxx whereas the the GTX 460 scored H95xx. Somewhere around 16-17%. GPU score it was like 9xxx vs. 10xxx, roughly 18% advantage for the 6870. So I'm guessing the 6870 being somewhere between 5850 and 5870 is about right?
