if portability is really needed for that "gaming" system.
(ignore the radiator, its not the macbook you are looking for).
This isn't really the point, its about being able to seamlessly transfer between gaming and non-gaming modes on one portable machine. Having two computers is a major pain in the ass. Say you installed a program you like on your laptop, and also want it on your desktop. You're going to have to go through the trouble of reinstalling that program on the desktop. Same goes for managing music and video libraries on both machines, its just a pain. Being able to have a laptop with great battery life and portability to use on the go, and the ability to plug in to a eGPU at home when gaming is desired is a great solution. You also have a bit more money saved from not having to use redundant components (i.e. SSD, screen, CPU, etc), so more can go into the system overall.
