Custom laptop specs for After Effects

You might want to educate yourself on how AE actually works. What would you even do with a ten core processor, of which only two will be used most of the time due to AE's limited multithreading? Conversely, what use is an RTX 2070 when a) AE itself is barely GPU accelerated and b) most accelerated third-party plug-ins at this point don't support a single specific function of this card. You know, most of them still use basic OpenGL and older implementations of openCL/ CUDA. Sorry, but your setup simply makes no sense for AE. You could easily shave off 2000 bucks with a less fancy system using a 4/6 core core7i and an older NVidia card. So if at all you go down that route, these specs would only ever be useful for gaming or a 3D program. Otherwise the old rule applies: You can't force AE to do anything by overpowering it with hardware. For more info simply read the gazillions of "How to optimize performance..." threads where I and others have explained all the details at lengths pretty much at least once every week over the years.
