If the refresh rate (which is measured in hertz, or Hz) is being called out as a feature on a given laptop, that means it's likely higher than the norm. Most laptop screens, including those in almost all budget models, stick to 60Hz, which means they redraw the onscreen image 60 times per second and thus can display up to 60 frames per second (fps) of in-game performance. (If your graphics chip can produce 90fps in a given game, you'll see only 60 of them.) Some notebook screens these days, though, can display at 75Hz, 120Hz, or more. These high refresh rates can be beneficial for some extremely fast-paced games, particularly titles played competitively online, such as Counterstrike: Global Offensive, DOTA 2, and Overwatch.
Dell is back in the market with their latest notebook in the form of Dell Inspiron 5575. This is an interesting variant from the Inspiron series of laptops from Dell, as it offers a very good set of specifications for the asking price. It sports a large 15.6-inch full HD display which is decent for gaming, and it is anti-glare so playing games for prolonged periods wouldn’t be stressful to your eyes. Moreover, it is fairly lightweight machine weighing just 4.8 pounds which is very good considering the kind of performance it offers.
The key thing here is to know what you're getting, and to make sure you have the appropriate port free (or that you have Bluetooth support). If you opt for a cabled mouse, don't forget to check the cable length. Is it long enough to reach from a PC tower on the floor to your desk? Is it six feet long, but only needs to run from your mouse pad to the laptop beside it? Also look at the cable itself. A braided nylon or cloth cover is more durable than a standard rubber coating.
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.
