It seems there are so many more choices now! I've been reliably using my iMac quad-core 27" for about 2 years and I recently started a new job where I have A LOT of down time where I could be using my computer to be doing much more at the workplace (I have a side hustle as a photographer, some light video). Also, I live in the country and my internet is terribly unreliable. So, I'm considering going with one of the 2016+ Macbooks, 13 or 15". I always got the 15" in the past because I wanted the performance. But now that calculus is different. Now I'm wondering if I should get a 13" dual-core and use an eGPU at home for times when I might be needing to do some serious processing (this eGPU could theoretically follow every upgrade down the road) or buy a 15" that's maxed out. What are people doing? The 13" is so much more portable, I have to say. And I'd probably be using an external monitor at home anyway, so the 15" might be lost on me there (for Lightroom, Adobe Premiere, etc). The one issue is the dual- versus quad-core difference. I don't think they make a 13" quad. Thanks for reading!
