I have personal experience with Audacity, it has had no problem for me except not loading all my media correctly. But, I have an AMD 64 2600+ 2.12Ghz Processor with 2 gigs of ram. :-/. So I couldn't tell you if your computer would work correctly. But, back on subject, Audacity is a great program but, It doesn't remove Voice from background, I don't think I have only used it about 6 times...
