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?
