You need to consider also that you might need a faster more capable computer. Processing D800 files are considerable bigger. Specially if you shoot RAW. I bought the D600. I upgraded (downgraded) from a D700 and I really miss the controls, 51 focus point and the better, beefier construction. But for the type of photography I do, a D600 is more than enough. At the end is what you want to do with the camera. Having the latest baddest is not always better for the type of photography you want to do. My two cents.
