I have a really hard time deciding between the new iMac 5K i7/8GB/512GB/580 and Macbook Pro 15" 2.9Ghz/16GB/512GB/560 + LG UltraFine 5K. I bought the LG UltraFine 5K in the spring and the plan was to buy the new Macbook Pro, because my current MBP 15" Late 2013 is lagging with the LG 5K. If I choose the iMac 5K I will also sell both my MBP and LG 5K, and it will be a much cheaper solution. I just finish my education as a Graphic Communication here in Denmark and I want to start as an independent, where I will work with Photoshop, Illustrator, InDesign and After Effects. The good thing about a Macbook Pro is that I can take it with me and be flexible. When I have a meeting with a customer I can showcase thing with my laptop, but I also already have a iPad Pro that can show my work. The good thing about the iMac 5K is that I can upgrade more than 16GB memory and it has a more powerful GPU. I dont know it I will notice any different between 560 and 580 software like Photoshop, Illustrator and InDesign with a 5K display. So the two option I have is: 1. iMac 5K + iPad Pro 2. Macbook Pro + LG UltraFine 5K + iPad Pro.
