I am looking for advice. I don't do any rendering or intense graphic manipulation on my computer. Mostly I use it for web browsing (10 to 20 browser windows) and productivity applications - Excel and Word for example. I do make use of Fusion to run one or two Win7 instances for applications not available on macOS. My current system, a 2015 MMBPr with the 16GB and the AMD 370x graphic upgrade works well with my single Apple 27' Cinema Display - non TB model, monitor. In short I don't do anything to tax either the processor or graphics subsystems. I ordered and received a new MBPrTB with the 2.7 CPU and the Radeon Pro 460 and two LG 5k monitors. This new system runs my applications workload well. I most likely will be returning the notebook because I miscalculated my disk storage requirements.
My question is: If I am going to have to reorder my notebook would I be just as happy with the Radeon Pro 450 or 455 rather than the 460? I will still use the replacement machine with the twin 5K displays. I think any of the processor options would be fine for what I am doing and I will switch to the basic Radeon Pro 450 if the 460 provides no value. I just hate to order a 450 and then find out I should have gotten the 460.
