If you do a lot of denoising (Is that even a word?) of your photos, I would highly recommend getting Topaz Denoise, or their trio of Denoise, Sharpen and Gigapixel, if you haven't already.. I've been using them for about a year, and couldn't imagine post processing without them. I could probably live with just Denoise, but the others come in handy from time to time. I do mostly wildlife right now, and often shoot at high enough ISOs that I need to clean them up. The added sharpening is a huge boost from time to time. I no longer immediately delete photos that are just a tad too soft, either from focus errors, or subject/camera movement.
The new automatic denoise feature of LR is not bad, but extremely slow in rendering. Also, Topaz denoise will sharpen at the same time as it performs it's denoise function. I don't often have to use Sharpen, if I run it through Denoise first. Adobe may come out with features in LR and PS that will rival Topaz, but they haven't yet IMO.
