I understand the temptation, and the moment of weakness...believe me. We all have it to some degree.

I would take Pro Tools over Garageband. I don't really think that’s good advice. You have so much more flexibility.

PT6 is Pro Tools 6. A later version than what you have. The latest version out is Pro Tools 7.3. I don't know that it would work with your computer, being an earlier model. There is a ton of information on digidesign.com and here on the DUC that you can access telling you what is compatible. You might try looking into that to determine your next step.
