Hi all, I am going to buy a MacBook pro and I am interested in eGPU possible solution for the future. Is there any difference between the two models in terms of eGPU upgradability? I know that the latest is tb3, could be this an important point to take in consideration or also tb2 could work well? Models I'm taking in consideration are the 15' 2015 model with iGPU (the one selling now on the store) and the new 2016 macbook pro 13' without touchbar. Which one should be the best buy with egpu in mind? Thank you for any input
