Have you considered other options?

I consider laptops of this class the worst of all worlds. They are too large and heavy to really be considered “portable”. Sure you could move them if you wanted to. At the same time, their form factor doesn’t dissipate heat well enough to realize the full potential of the specified hardware.

Other options:

1. Get a desktop. Maybe not practical if you aren’t always working from the same place. IE. Sometimes at home and sometimes in office. You could almost certainly build a desktop for less than equivalent advertised specs in a laptop form factor.

2. Spend ~$1.5k on a mid range more portable laptop and ~$1.5k for an eGPU on a desk. You still have a laptop to bring around places and you have more horsepower somewhere when you need it.

3. Spend <$1k on a laptop and connect to cloud services
