Hello guys, I bought a new MacBook Pro 13.3" this weak. But I discovered that the device is an 2016 Model and is neither Early nor Mid 2017 Model. In other words, my device comes with the older Intel processors with integrated Intel Iris 550 Graphics Card. Whereas the new Model of 2017 comes with the new structure Intel processors with an integrated Graphics Card of Intel Iris Plus 650. The newer model costs only 50 EUR more. My question: is it worth it to bring my device back and replace it with the newer model for only 50 EUR more? Is there a huge performance difference between the two models? What would the exact difference be? And as of graphics, is the Iris Plus 650 a lot better than Iris 550 in medium gaming and in video processing? Thanks a lot!
