For proper functioning of GPU, it is essential to have VRAM of their own. This is beneficial in storing different frames, textures and other required properties for getting frames for the monitor. Finding out how much you require may be tricky. Hence, it is better to go for a laptop with as much VRAM as possible. You can buy a laptop with 3-4 VRAM. If you have reduced budget, you can opt for 2 GB VRAM. You, however, need to ensure that the resolution of the gaming laptop is 1080P.
Budget systems usually reach their attractive prices not just through the balance of build quality and components, but also from bloatware. Having junk like Norton trials and eBay apps pre-installed translates to revenue in the PC maker's pocket, allowing them to hit aggressive prices. So, know going in that you may need to do some uninstalling once you've unboxed it and fired it up.
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.
However, I found that that the Rival 500's generous controls may also contribute to its biggest problem: a lack of weight. As with other mice with 10+ buttons, there's just not much heft to the body of the mouse itself. With no option to add more weights, the mouse feels feather-light, and not in a good way. This isn't a huge issue, especially if you like lightweight mice, but it's the cost of essentially having a keyboard in your right hand.
At this point, the major mouse makers' software packages have been through generations of refinement, so they are slick. Logitech Gaming System (LGS), Corsair Utility Engine (CUE), and Razer Synapse are three of the best-regarded mouse- and keyboard-control utilities that cater to gamers. All offer advanced tweakability, with CUE regarded by many users and reviewers as the deepest, but also the trickiest to master in-depth.
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.
