Anyway, I did find some minimum requirements to run the new Sonar (which should be fine with X3 as well):

If you're not going to use a lot of soft synths & Fx's, that laptop should be more than sufficient. Of course, it's good to have more "power" under the hood when you need it, but I totally understand you're on a budget.
