One of the perks of living in the 21st century is the constant stream of technology that is available for us to use. The majority of people know how to use laptops and computers, but most of us are not computer wizards. The majority of people use simple computer skills for work and leisure purposes, whom I would define as an average computer user. As a college student who uses the internet for leisure and study purposes as well as basic Microsoft Office functions, I would classify myself as an average computer user. Thus, I am writing this review for the average computer user.
So, what makes the difference? Comfort and accuracy come more naturally to some models than others. An extra button in the right spot can speed up switching modes or weapons, saving you life-or-death fractions of a second. And the right supporting software can power simple or complex shortcuts that decide defeat or victory. Here's what to look for in a right-fit gaming mouse.
Still, unless you're attempting to become a professional gamer or get ranked globally in a particular popular title, a 60Hz screen will suffice. Nearly all gamers are still "stuck" with 60Hz displays, after all. High-refresh panels aren't common in budget machines, but they are worth knowing about, as we expect them to trickle down into under-$1,000 machines soon.
G-Sync or FreeSync: Several gaming laptops come with panels that support Nvidia's G-Sync or AMD's FreeSync technologies, both of which are designed to eliminate unsightly graphical tears and ghosting 0n monitors ranging from 1080p to 4K. While 60Hz is the current minimum refresh rate, there are an increasing number of monitors that offer 120Hz, which offers even faster rendering without introducing stutter. 
Gaming laptops can put a serious dent in your wallet, with some of the fancier models costing upward of $3,000. But who says that the right rig has to cost an arm, a leg and the soul of your firstborn? Fortunately for the fiscally conscious gamer, there are some sub-$1,000 notebooks that can run graphically taxing games like Destiny 2 and Shadow of the Tomb Raider at solid frame rates.
