Mainstage and Logic HELP!!

I am currently running Mainstage and Logic Pro X. I love both, but my current computer is running very slow. So I have decided to buy a new laptop, but I want to know what type of core I need to allow the aplications run to its fullest. I know what they reccomend, but what would be the best to put in it.

P.S. I am planning on adding Ableton Live and a few other softwares to improve my stage.
