I have Virtual D.J. 5.2, while you have Numark Cue, which is Numark's branded version of the same software.
Yes, I like it, very much.
I'm using a Gateway on Windows, and a Macbook Pro on OSX. These are only two of MANY choices you could use.
I'm certain that "what you need" is clearly laid out when you purchase the software, be it on a retail box, or the download website.
If you can ask a more specific question, I'm certain we can assist you better.
