I have a 2014 15" MBP, but am considering downsizing to the 13" whenever the 2017 models come out. I'm primarily a front end web/app developer, for which the 13" is plenty powerful. I plug into an external display when doing any serious work, so screen size isn't an issue. However, I do occasionally have to use After Effects to animate and render short video clips. Does anyone have experience with the 13" and AE? Does it work well enough, or is it worth it to go with the 15" for the dGPU?
