High end gaming laptops are a curse. It's a package that cannot be performant, you simply don't have a good space to cool it and keep it portable. Focus on it has made a big part of development in good hardware to be restricted to space and heat efficiency in a non optimal package.

Desktop is the way to go for gaming, you get much more affordable power and bang for your buck. If you want a machine for gaming you want a space where you can chill out and be confortable, desktop on a table with a good chair and nice monitors are the way to go and cheaper than the laptop counterpart.

Laptop is pretty handy for taking it to wherever you need it. But you cannot enjoy that high end performance on a comparatively tiny screen. If you are just carrying you laptop from desk with monitors and keyboard to another, you're just using a less effective and expensive desktop in two spots.

Even for working, it's handy to have a way to take your stuff elsewhere, but the way workstations work you'd much more benefit from having a cheaper desktop at you office and/or home and have a notebook to stream the content you need.

All the while all the money and research spent on high end laptops and graphs cards that live in them is being used to fuel a worse product that will invariably overheat and not work at full capacity.
