I write this as awareness warning not as lament:

So , I have Asus rog g752vy with i7 6700hq + 980m, at the time I bought it was 2150 USD, I used most for graphics work, and less for games.
Now, after 1.5 years of use, I started to see two big hue/color stain starting to spread on the display, I wait, though it is software problem, reinstalled the OS, put linux, so on, was hardware issue with the display.
I called the Asus Service Center (the laptop still had warranty) on 08.12.2017, they put me in touch with a asus service from another town( here the law it is than in 14 days I must have a result, money or the fixed part back, because the december month it is a slow in work at me, I though it is good to send it).
The mail company take my laptop on 12.12.2017 after a lot of calls. On 20.12.2017 I got it back, and as I was fear, they resolved my issue and broke another 2, now I had 2 white stuck pixels on the center of the screen and the G-sync don't work anymore.
I called back to the service, they treat me like i was a thief, and I was supposed to say thank for what they did.
After more calls and emails, I call the Asus Rma Center, they put me in touch with another service from another town, again need to explain the problem, so on.
I got it back resolved, as it shoud be from begining (the display need to be changed) on 04.01.2018, so they need it almost a month + a lot of energy +calls+ emails from me to fix it.

All this time was a light winter, no snow + over 5C.
Meanwhile I had had to work on a low 15" laptop, because my clients don't wait for my service, and the experience was bad(the screen had colors abberations).

So what I learn:
- if you buy a expensive/premium laptop from Asus, if need RMA, they will treat worst than a usual product customer
- need to have tech savy to not get burn by asus service + a lot of patience and time/energy
- some services know less about products than they should
- Asus have a shady way to use g-sync in the laptop, my display was replaced with almost same model(with a g752vs model), the only difference was that mine had 1 at the end on model number , the replaced had 3), so they white list a combination of mbd+cpu+panel for the g-sync to work, this mean that you can't replace that display (if any issue arise) with anything else that fix that model.
- in same amount of money I got a powerful pc(i7 8700+ gtx 1080), if you don't need portability, don't buy a laptop
- the software/firmware issues on asus laptops are slower to be resolved(if will be) than other products(like a motherboard)

I don't think the asus products are bad, but I think the support it is bad(funny thing it is that now I have a Asus mbd in my new pc, and happy about it, but wasn't my 1st choice, not even 2nd, was the 3rd choice, I wanted a gygabyte, then a asrock, but was out of stock), so for a while I will have this in mind when I will buy something from them(if).
