All the laptops I had were always at least 20% slower than desktops built on similar components while being much more expensive. This should already make you think twice before you buy a gaming laptop.
If you think you'll be able to enjoy gaming and travelling at the same time you're wrong. You'll face connection problems and slow internet in hotels and will need to find a decent chair enjoy gaming and desk to fit your mouse pad (can be harder than you might think).
Just buy a decent smartphone and play sims or something while you're away from your beloved PC.
I couldn't agree more.
