Yours is a very common question now that "affordable" FX cameras are available(used D700 or new D600). I would say there is not enough information to give a good answer, so much depends on subject matter, style of shooting, display media and not the least of which is, how much long term commitment to acquiring the lenses that these higher res new cameras deserve. The body is the very cheapest aspect of moving to FX. If a survey of FX shooters was taken you would probably find that their lenses total about $10,000 and much more if they are into sports, wildlife and worst of all, birds-in-flight. Shooting above 800 ISO generates noise you do not like. OK, what light conditions are you in, what shutter speeds are you needing for the subjects and do you exploit augmented lighting to its best advantage? The D7000 will give a stop advantage and at low ISO, very few cameras ever made are lower noise...only newest Nikon models, D800, 600, 4, 3x. If you stayed with DX, as most people should, there is none-better than the D7000. Your 18-200 is causing some of that noise by having to shoot higher ISO than the scene would normally need with faster glass. Can you post a photo or two which shows typical subject matter and lighting conditions? That would help in giving either camera change advice or technique advice to get the most from what you have.
