    Deciding the specs of my first-ever Mac. 2015 MBP.

    I do mainly 3D modeling and photo-rendering. Most of my software can only utilize NVIDIA GeForce (CUDA) graphics cards. So for that, the AMD Radeon has no benefit. And may be a hindrance.

    I plan to use the MacBook Pro as is for a while. And add an eGPU with GeForce GTX 1070 when the time comes.

    Knowing that, is it still better to get a MBP with the Radeon GPU card inside? Or no dGPU and only Intel Iris?

    I heard eGPUs work easier on MacBook Pros with no dGPU.

    organicCPU said some Photoshop functions are gone with no dGPU.

    What else would I be missing with no dGPU? (and not yet any eGPU)

    Any thoughts or recommendations?

    Most obviously the 3D features in Photoshop (CS6) are missing without dGPU.

    I do not know about missing features in Photoshop without dGPU, but I can confirm that it is easier to setup an eGPU on a machine that doesn't have a dGPU (It is possible to setup an eGPU on a machine with dGPU, but be prepared to do some extra steps to make it work). Also a machine without dGPU has one less component that can break and better battery life. If you however need graphical performance on the go, a dGPU will be the best choice.

    Can anyone give any indication of the difficulty or steps involved in setting up eGPU on a MBP with dGPU vs without a dGPU?

    Anybody know roughly the battery life with and without dGPU?
