Hello, I am in the market for a new laptop. I am a web developer/designer, so I will be using Photoshop, Illustrator, Dreamweaver, multiple browsers and browser tabs, often running at the same time. There may be some time where I would be editing very short web videos, but nothing major. I would also like to use it for Steam in-home streaming/light gaming and entertainment purposes, i.e. HD video files and music files (both streaming and locally). Edit: I will also be using an external monitor at work. Not a big deal, but I thought I would mention it. Can I get away with the MacBook Pro that has 2.2GHz quad-core Intel Core i7, 16GB RAM, 256GB and Intel Iris Pro Graphics or should I go with the same model that has the 750m discrete GPU? Thank you in advance for your help!
