Maybe OP is a fgt, or maybe he doesn't have the choice...
I'm in the second category, i move often, and i can't have a desktop. (it's really useless to have a pure built PC, that you can touch only once every months :'( )
So i have a MSI GT70 2OC i7 4700MQ 8Go 770m.
OP ask for Gaming Laptop, and he should look here:
notebookcheck.net/Notebookcheck-s-Top-10-Gaming-Notebooks.98628.0.html
OP don't listen to those angry kids, not all gaming laptop overheat (depend on your choice).
Don't take those "ultrabook" like Razer, those shit could cook your finger while playing.
If you want something specific, look here:

Shenker, let you make the choice of compounds in the Laptop.
They are a little bit more expansive, but you know what's IN the PC, and if there is a problem, it's very easy to repair, and free if you have a screwdriver ;)
This laptop can also be upgradable (including CPU and GPU, but this two aren't easilly to upgrade, you really shoold ask to a pro), SSD, RAM are easy access!
All of this depending on your money, cheap => look at MSI, ASUS (avoid "ultrabook", 4K display, Gsync, FreeSync... Useless on laptop).
If you got money, go XMG, and make your own.
if you don't know what hardware you neek, check their Forum ;-)
Also the Asus you showed us, is a good choice if you play not big AAA game (he still handle FO4 on high)
If you search for something durable, it's not a good choice.
On notebookcheck, you can see for each GPU, many game test with FPS and settings.
A last advice: wait few month for nextgen GPU NVIDIA/ATI, the price for old gen will drop ;-)
