For a long time, competitive gamers strongly preferred wired gaming mice to wireless ones to eliminate perceived latency, as well as the possibility of a battery running down in the midst of a heated match. Many serious players still hold that bias, but Razer, Logitech, and others have released higher-end mice of late with low latency ratings that ought to satisfy at least casual gamers.
Looking for something more bleeding edge? A new version of the Razer Blade just came out. It features an 8th gen Intel Core i7 processor, and starts at $1,900. In its review of the 2018 Razer Blade, CNET gave the machine an 8.6 overall, bemoaning its high price but saying this rig "moves the bar on slim gaming laptops, with better hardware and a bigger screen."
These budget systems typically won't include a lot of gamer bling like customizable RGBs and multi-zone keyboard lighting. Many will cut necessary cost corners by using a plastic chassis instead of aluminum, and you won't see sexy thin bezels like those on the MateBook Pro or Dell XPS 13. You'll also get, at minimum, 3 USB ports, an HDMI output and standard headphone jacks.
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.
