Help - Lenovo 520s or 720s?

Hi!


This is my first post here and I'm looking for some recommendations.


My old Dell XPS14Z just died after 5 years and I need a new laptop


I basically use my computer to work and to DJ. I use traktor and ableton. I wanted to buy a Mac, but i might be a little bit too expensive and as much as my first Dell was amazing, the XPS had many problems. So I'm thinking of switching to Lenovo and this are my 3 favorite options.

Ideally, and for DJ matters, I think a 14'' screen would do better. And so for the cheaper price the 520 could be my best option? What are the differences between the 720 and the 520?


I'm texting from a Inspiron 5000 13 that I bought today and I'm returning this piece of crap. Looking for recomendations and open to suggestions. Thanks a lot!!
