My Old model is a mid 2012 macbook pro 15" non retina. I want to buy a new 2016 model, but I'm not sure which model. The 13" or 15". At the moment I'm using FCPX and Photoshop sometimes. This would be no problem for the 13". The only problem is that I use parallels for school to run Autodesk Inventor 2017 and I don't know the dual-core and the graphics are good enough in the 13" model. I would take 16gb of ram and 512 ssd but I'm not sure about the model.
