Full size gaming PC for me, an expensive inferior gaming PC with very limited upgrade potential is just no substitute.
I don't get to game much since I got married and became a dad but I wouldn't give up my Octo cored cpu and 1080ti cooled by water pumped through two large 360 rads with nine 120mm fans cooling the whole affair for any current laptop or console .... Despite what @glaucous thinks you cant anywhere get close to that power in the form factor of a laptop be it a 'gaming' one or not. Sure not all games need masses of power but when I do get the time to have a play I want to have the power on hand to enjoy all recent titles.
Also why anyone would want to swap out a decent, large desktop monitor for a pokey laptop one is also beyond me.
Probably about 70‰of my Internet browsing is now done on the phone though!
