Nvidia's G-Sync and AMD's FreeSync technologies are more down-to-earth. They help increase the quality of the gaming experience and smooth out frame rates by letting the laptop screen refresh at a variable rate that depends on the output of the GPU. Look for support for one of those technologies if you're a stickler for perfectly rendered visuals. They tend to be in pricier machines, though, and G-Sync is far more common.

NEWARK, Calif. & LAUSANNE, Switzerland--(BUSINESS WIRE)--Logitech International (SIX: LOGN) (Nasdaq: LOGI) today announced that it has closed its acquisition of ASTRO Gaming, a leading console gaming brand with a history of producing award-winning headsets for professional gamers and enthusiasts. Logitech first announced its agreement to acquire ASTRO in July 2017, as the Company invests in an adjacent gaming market — the console gaming market.
Resolution: Never get anything less than a 1920 x 1080 display. It’s rare to find one with a lesser resolution, but if you do, run. If you have a GTX 1070 or GTX 1080, you may want to consider a 2560 x 1440 display. 4K (3840 x 2160) screens are an option on some gaming laptop, but it’s rare you’ll be able to both get enough graphical fidelity at that resolution while also maintaining a smooth frame rate.
More the issue is knowing how your mouse connects to its host. The three main possibilities are USB (via a typical cable), USB (wirelessly, via an RF USB dongle), or Bluetooth (also wireless, usually via the host's built-in Bluetooth radio). Bluetooth is the least common of the three in gaming mice; it tends to be found more often in productivity or mobile mice. Note that some wireless models with rechargeable batteries come with a USB charging cable that can double as a mouse cable while you're juicing back up, letting you continue using the mouse with the battery depleted.
The entry-level TUF Gaming FX computers (which have recently replaced the old FX product line) have the particularity of being available in four different configurations; each configuration features a rather sober-looking chassis and a display operating at a frequency of up to 120 Hz. Laptopmag’s test confirms the good performance characteristics of this computer and the good quality of its speakers which deliver powerful, high-def sound. However, it also mentions its disappointment with this computer’s display (a 60 Hz model) as well as with the performance of its SSHD.
In my opinion a Core-i5 CPU with a GTX 1050 Ti graphics card is the sweet spot for medium to high quality 1080p gaming. This means that even with visually demanding games you can crank up the eye candy and still maintain 30 to 60 frames-per-second. The GTX 1050 is capable too, but you'll need to crank down the quality knobs to maintain high framerates, normally to low or medium.

Planning on spending hours upon hours handing out beatdowns in Fortnite or Call of Duty? Check out the Dell G3 15 Gaming laptop, which lasted an impressive 6 hours and 37 minutes on our battery test. Gamers also get a system capable of kicking out some solid frame rates and good sound, thanks to a GTX 1050 Ti GPU and some powerful speakers. And at 5.2 pounds and 0.9 inches thick, this is one of the thinnest entry-level gaming laptops available.
