I use Capture NX (previous version before NX2) to process RAW files from my D80 (and my old D70s). It is an excellent programme for basic editing and manipulating RAW files. I do not do much processing thought to be honest, have no need for photoshop for day to day use. Use Capture NX to crop, tweak settings such as light levels, white balance etc and to output to hi res jpegs. I would certainly recommend it for basic tweaking of RAW files, if you need to do a lot of editing the you might be better off with Photoshop if you can get the plugin for your camera model.
