Resolution: The minimum resolution for any gaming laptop is 1920 x 1080 — anything less and you're asking for muddy graphics. Laptops with QHD (2560 x 1440) or 4K (3840 x 2160) panels are becoming increasingly popular, praised for their striking details and color. There are some gamers that swear by 1366 x 768 because of the increased frame rates, but I implore you to love yourself more and aim a bit higher.
Best Portability (13 - 14 inches): If you're constantly on the move, you'll want to consider 13 or 14-inch laptops like the Razer Blade. Notebooks in this size range typically weigh under 5 pounds and tend to have longer battery lives with an average endurance of 7 hours and 38 minutes. However, 13 and 14-inch gaming laptops usually don't come with the most powerful CPU or GPU, because they just don't have enough space to dissipate all that heat.
You'll want to make sure you get the most graphics power you can afford from the start since this can't be upgraded later, unlike memory or storage. If you're on a strict budget, go with one of Nvidia's Geforce GTX 1050 or 1050Ti graphics cards, which will give you good performance on newer games at medium or high settings with prices starting down around $600. If you can afford to spend closer to $1,000, you'll be better off in the long run getting a laptop with an Nvidia GeForce GTX 1060 Max Q with 6GB of memory.
Another spec to watch for is panel type. You'll want to go for an in-plane switching (IPS) panel if possible, as they generally offer the best off-center viewing angles and colors. Some gamers are content with cheaper twisted nematic (TN) panels, which make you settle for narrower viewing angles—but then, you're probably seated directly in front of the screen, so that's not an issue. TN panels can offer slightly faster response times.
Know that the presence or absence of a dedicated control utility is a big differentiator between low-end and high-end gaming mice. Some cheap gaming mice will come with no software of their own. Without such a utility, you'll be able to customize mouse commands only within a game (via its in-game menus) or in Windows' own mouse settings. That's not necessarily a bad thing; just know what you are getting, or not getting.
Look for Intel Core i5 processors in midrange systems, with Core i7 U, HQ, and HK processors in higher-end gaming laptops. The H-series processors are higher-power, and tend to show up in bigger, thicker laptop models, while the low-power U-series chips are designed for thinner, more portable machines. They are quite different, in terms of thermal profile, as well as overall performance potential; a U-series Core i7 processor may not even have the same number of processing cores as an H-series Core i7 chip.
Laptops have become indispensable nowadays and have become an integral part of almost everyone’s life. Apart from being used for work, there are laptops which are made specifically for gaming. Gaming laptops are high performance computers and deliver amazing visuals that are needed to effectively run your games and enjoy them to the fullest extent. The laptops produced nowadays are powerful enough to run high-end games seamlessly. When it comes to gaming laptops, popular brands such as Alienware, Acer, HP, Dell, Lenovo, and MSI rule the roost.
