The D3200 has a little better high ISO performance than D90, more Dynamic Range and significantly more Color Depth as well. It also has twice the resolution of the D90. The D3200 doesn't have a sub-command dial, penta-prism viewfinder, or dedicated buttons to quickly change settings without going into the camera menu that the D90 has. So there are trade offs. Good Luck and Enjoy your Nikons!
