Question: I haven't seen a quorum on this topic so I'm raising the topic and if anyone else has an opinion let me know.... I'm buying a 15" rMBP when they come out and am seriously considering buying the 2GB dGPU. I know the answer depends on what I do - I'm not a gamer, occasionally photography (Photoshop) and video only. Already planning on 16GB RAM.I could take that money and upgrade the storage. Is the dedicated GPU worth it for a non-gamer?
