I5 or I7

Hi guys
i'm searching for a notebook which i would use Djing (Mixvibes DVS 7.2) and music production (Ableton).
Now i'm not sure which processor ist better for my purposes: Intel® Core™ i7 720QM or Intel Core i5-520M. Does anyone know how much cores are supported by mixvibes and ableton?
would it be better for me to choos the one with the I5 or the one with the I7?
