d800 on automatic

Ok, my cluelessness about photography astouded even myself. Lol....

In any case, the reason I want to upgrade from my d90 is that it's a bit blurry in low night and indoor conditions. Due to the increase in the CCD size when I upgraded from a real point-and-shoot to a dslr, the difference shooting in those conditions was amazing.

Will an increase in I,age quality whe I go from a d90 to a d600 or d7000? Basically, my perfect camera would be me a black box with just one button (the shutter) and a giant CCD for great indoor image quality.
