Not that I want to dampen your enthusiasm for getting a K-5, but your NR adjustments shouldn't be turning your ISO 1600 images into watercolours. How far are you cranking the Luminance slider? I avoid going over 40 with that no matter what the ISO. Try pulling the Color slider all the way to 100; that's safe and often removes the nasty banding you get with the older sensors (*ist and K100).
But if you have an ISO 1600 shot and you try to boost the shadows too much, nothing will help you. Make it a B&W and the noise becomes A Feature.
