I believe the lens advantage you're speaking of is more due to the resolution of the D600 vs. the D300 than it is to FX vs. DX - that is, you seem to be talking about shooting the 24-85VR on the D600 (at 24MP) and then comparing the result to the D300 (12MP). To do a fair comparison, you'd downsize to 12 MP, and then I think I agree the D600/24-85 shot will probably look better than the D300/ 17-55 shot.

the advantage comes from both more pixels and larger sensor.

For example when using 50 F1.8D, D700's resolves 10mp while D300 resolves 8mp, despite both sensor has 12mp.

I don't take the DxOMark ratings that literally, myself - I don't think they mean the same thing once you mount the lens on two different bodies. I only use them for relative comparisons on the same body.

This is not to put down the 24-85VR; I have it and use it quite a bit on the D800, so I'm familiar with what it can do on that body; but I think if you shot it on the D700 and compared the results to those from a D300 with the 17-55, you'd probably be more impressed with the shots from the latter combo.

I would disagree. 17-55 is on average one stop faster than 24-85, but D700 is more than one stop better than D300. Also 24-85 has VR.

It isn't just a matter of any one measure. The 17-55 has better micro contrast than the 24-85, less distortion, faster focus, and nicer rendering of out-of-focus areas. The 24-85VR is a real bargain; the 17-55 is still a better lens overall, in my opinion, having used both of them a lot. But it's not a true FX lens, so it's not the most convenient to use on FX, despite the fact that you can make it work, as I've described above.
