I used to think small form factor cases with powerful desktop-grade components are the way...
But then 2018 gaming laptops changed my mind. I have one now.
- 6 core with up to 4.1 Ghz turbo, Dual-channel DDR4- 2667 (and faster exists, up to 3200)
- GTX 1060 full throttle (overclockable) with complete 6 GB of fast GDDR5
- M.2 SSD + Extra 2.5" drive (or SSD)
- 144Hz screen, IPS
This is my laptop...

I would say it's a freekin' amazing score and performance for ANY computer, let alone for a laptop.
I think 2018 is finally the year when laptops are no longer visibly slower than similarly desktops (including monitor).
And of course there are models much faster than mine, with GTX 1070 or even 1080 !!!, and very recently with 2000 series (but of course, more expensive)
@MIRTAZAPINE 's solution as a travel computer is very outdated and inconvenient.
