The answer depends on your preferences and your finances, I would say. If you care a lot for getting the tiniest detail in your images, the d800e might give you, if nothing else, just a better feeling in your guts. But then, when I bought my camera, the difference between e and non-e was - in Germany - about 300€. Now it is 700 or so, and if I would have to buy a camera today, I might reconsider. But this is also a question of how deep your pockets are.
