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.
If I was buying a gaming laptop I would buy one with a great screen and a fast CPU with an integrated GPU. Then buy one of those separate External Graphics Card Docks. You can put whatever GPU you wanted in there and could readily update your GPU. This would give you a great laptop for everyday use and when you thought you needed to game somewhere you could bring the External Graphics Card Dock.
Gaming laptops need to have the necessary processing power to run high-end games. Laptops with good processing speed help run your games seamlessly without any lag. When it comes to a CPU, the important elements to be considered are the number of cores it contains and its processing speed. A laptop with a powerful CPU ensures a lag-free gaming experience.
Of the gaming laptops we researched and tested in 2017, the Acer Predator 17 G9-793-79V5 has the most powerful specs for the price, without any dealbreaking flaws. The Predator 17 keeps its WASD keys, underside, and components cool, and it has a comfortable, responsive keyboard and a great 17-inch 1080p IPS display with G-sync. Its biggest flaws are loud, distracting fans and an ugly, haphazard-looking keyboard. Most important, the Predator 17 will be able to play most modern games on ultra settings—it offers great performance for the price. (If you want to know how it will handle a specific game, take a look at Notebookcheck’s benchmarks database.)
A gaming laptop is constrained by its graphics processor; that’s the component that has the biggest impact on gaming performance, and you can’t upgrade it. Many cheap gaming laptops also lack either a solid-state drive or a roomy hard drive for storage, so you may have to pay extra to upgrade that later. You’ll need to put more money into keeping a budget laptop relevant in the long run—through storage and memory upgrades—than you would for a high-end gaming laptop that already has a solid-state drive and at least 16 GB of RAM (not to mention better graphics). A cheap gaming laptop is a temporary fix for a couple of years if you can’t invest in a desktop or a more expensive laptop (or if you need something that’s moderately portable).
Fortunately for anyone interested in acquiring a gaming laptop with decent battery autonomy, there are a number of models on the market that have highly optimized hardware configurations like the Asus ROG Strix Hero II (which has almost 5 hours of autonomy), the Acer Predator Helios 300 (approximately 6 hours 50 minutes of autonomy) or the Dell Inspiron 15 7000 (around 7 hours of autonomy). This last computer takes advantage of Nvidia’s Max-Q design in order to allow its GeForce GTX 1060 graphics chip to consume less power while remaining fully capable of gaming in Full HD. The Alienware 13 (OLED) also has a battery autonomy in excess of 7 hours (tested using office software).
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.
