Hi all, Soon I will go to the US for work and want to buy a new macbook pro 2018 because in Germany it will be 20% more expensive, about Euro 3800 EUR = 4447.99 USD US Dollar rate by 1.17 Ideally, I want to buy what is in the picture, but this is an additional 700 dollars, very expensive. Questions: 1. How much i7 will be i9 in performance? 2. Will I be able to upgrade the RAM in the future if I initially buy 16GB? If there is anything better for this money, I'm ready to listen to you. Write.
