Hi, as far as I recall, when the MBP 2018 first came out, some of you adviced going for the base model due to thermal throttling of higher end CPUs. Few months have passed. How is going with the i7 2.2GHz and 2.6GHz on the MBP 2018? From some reviews, am I correct that the 2.2GHz and 2.6GHz models perform almost the same but sometimes having 560X is better than 555X. If I do not want noisy fan nor heat issues when doing productivity work, watching 4K videos on youtube and using it to drive an external 4K monitor? Which CPU and GPU do you recommend? How much longer is the battery life under High Sierra, Mojave and Ubntu Linux when using the 555X vs. 560X and 2.6GHz vs. 2.2GHz? I am interested in 16GB RAM with 1TB SSD.
