I use Amadeus Pro, which is excellent but is commercial (paid) SW, although inexpensive, but with regard to Audacity, I have tried it and had dropouts, which is in my world inexcusable, so it's off my list. The problem wasn't hardware-related (other recording SW worked fine) and I haven't tried it on my current system (i7 Quad Core 2.8 GHz, 16MB, 512 SSD) but the system I did try it on was a quad core and had adequate RAM and free drive space.
