In any other case I would strongly suggest a desktop, but since you're in Korea it's not wise.
RoG and Alienware are wise choices for gaming laptops, but MSI GT series is good as well. Before you buy one, make sure that it has Nvidia 970M or 980M as a GPU. Anything lower than that won't do.
MSI sucks dick. I have a msi gaming laptop and it randomly shut down within warranty period, absolutely unresponsive to anything. Their service sucks dick too, hard to reach, site is bad and not even native language support (and when there is a native language part supported they tell you to write in english either way cuz they cant understand you)
Refund that shit. Doesn't even have to be within the warranty period. When something you bought doesn't have the characteristics as described by the seller you're allowed to rescind the purchase agreement.
Wish i could, i bet their service is like fuck no and what am i to do against it. I've had more problems with this laptop than just this breakdown but this was the last drop that i could endure from MSI.
I sent it in for warranty repair, they gave me an invoice saying 'we're going to replace the keyboard *picture of miniscule rust spot under keyboard* heres a 160eu invoice oh and no warranty cuz this is water damage' > they didnt even bother to try turn it on (cuz it doesnt fucking turn on) cuz the internal sucks and fried or something
So yeah im having my retailer yell at them for bad service atm and hope they'll actually look at it or i'm fucked (cuz i need the files on the laptop for my exams in 2 weeks)
I bought my desktop 4 moths before my mother got her laptop, the laptop is already fried, my desktopbaby is still alive and powerful.
Even if you get the top specs laptop it won't be as good as a desktop. You may spend less for laptop and have few advantages initially(like comfortable to bring wherever you want) but those will be just a memory within a year or so.
