Thanks for posting the comparison pix. Very helpful. Another interesting comparison would be to take identical pix at 6400 ISO with both cameras using a DX lens (such as an 18-70mm) to compare the noise level. Of course, the D700's files would only be 5MB shooting with a DX lens, so one would have to adjust accordingly with the D300. My D700 is due to arrive next week and I will be making similar comparisons. It will be so nice to be able to shoot at actual focal distances with my favorite lenses -- Nikon 50mm f/1.8, Nikon 85mm f/1.8, Sigma 24-60mm f/2.8 and the Tamron 70-200mm f/2.8.
