Better buy a model that has an external graphics card and never plan on it being mobile. Also plan on cranking every setting to performance on it too.
I really suggest getting a dedicated workstation. You need the raw horsepower of a desktop if you want to do real work. As much as I wish laptops had what it takes they simply don’t yet. Mainly because of the limited graphics capability which is actually improving a lot these days and also mainly because they run on a battery and heavy workloads will drain them super fast.
