D800 versus D600

At some stage I will buy one of the above cameras. I will use it a fair bit in DX mode as I do a lot of macro work. So, in terms of DX mode, were I to print at A4, would I see any difference between prints taken with either camera? My guess is that the 10MP from the D600 is more than enough, but maybe someone with experience can add insight.

As for other features, well I tend to use manual focus, and I do not print big, so either camera would be fine for FX shooting. I prefer the build of the D800, but the D600 is probably good enough, and the square viewfinder surround is better as it is easier to fit a right angle finder. The D800 has the annoying screw thread connector around the eyepiece.
