Looking to buy a new gaming laptop, which brands are reliable for long term use? My budget is around a 1000USD equivalent (I'm not in US) . Reliability of not having damages and repairs in foremost for me at this budget.
I'm going to say that unless you're willing to game at 1080p at medium settings, your not going to find a lot in the 1000 USD range but you can find some laptops like Asus F15 with gpus a few generations old that might fit your budget.
As for brands, just stay away from the corporate computer brands like Dell, HP, Alienware (literally Dell) and you'll be fine.
I still think you'd be better off building a desktop because even those laptops older laptops are pricy and there's no upgradability but yeah I'm sure you can find a something that will push 1080p with a 15 inch screen for 1K.
Wish I could recommend one to you but I haven't looked at gaming laptops for quite a while but I own two older MSI and Asus ones which were solid laptops with no major issues that are still running after nearly a decade.
