Well NV have a typical margin of ~40~50% so that means a 60% yield would be about right.
I think it's fairly easy to assume ATI are making more profit though, although how much more is another matter, and it also depends on volumes, especially when the GTX460 is at a lower price point (while only the HD5830 fits in the same point).
