I'm looking at upgrading to a newer Macbook Pro from my 2012 which is starting to feel slow particularly for GPU tasks. What is the best model that's been released in the last 4 years? I was looking at the 2015 but it's practically the same as my 2012 (4-core i7). Is the 8-core i9 actually going to work? I've read it's useless because of the heat issue: https://www.leafandcore.com/2018/07/21/apples-new-i9-macbook-pro-is-reportedly-slower-than-the-i7/ https://www.leafandcore.com/2018/07/21/apples-new-i9-macbook...
