RAM: Gaming can be RAM intensive, and 8GB is what we recommend for even average productivity tasks. If you can, you should go for 16GB on a gaming PC. A laptop with a GTX 1050 or 1050 Ti usually comes with 8GB. Once you get to a GTX 1060 or higher, some will come with 16GB of RAM. If you can’t get your laptop with 16GB of RAM now, consider upgrading it in the near future. Memory is upgradeable in many gaming laptops, so this is an area that you can consider boosting later if you’re handy with a screwdriver.
Less-expensive mice tend to have optical sensors, which offer good tracking sensitivity and tend to map well on a variety of surfaces, including textured ones such as cloth. Laser sensors, on the other hand, map onto the same or more kinds of surfaces (including some smooth or glossy ones that may give optical sensors fits), but they can be more finicky about rough surface textures. That said, we wouldn't let one kind or the other be the main reason you choose a mouse. Likewise, some vendors market branded versions of sensors that track, say, on glass or reflective surfaces. Don't take them too seriously, as you can solve any challenging mousing surface with...a $2 mousepad.
Lenovo dialed back the design on its latest gaming laptops to help them compete with Razer, but without the higher prices. The Legion Y530 starts at $750 with a GTX 1050 or $840 with a 1050Ti. Unfortunately, there currently isn't an option for a 6GB GeForce GTX 1060 GPU, but if you're willing to step back to its Y520 predecessor you can get one in that model for $1,099. 
At the moment, the most widely used display panel technology is IPS, which offers better color rendition and better viewing angles than TN display panels. Moreover, while the vast majority of displays operate at 60 Hz, there are a few displays – like the one on the Acer Helios 500 – which operate at 120 to 144 Hz. Some displays are even G-Sync compatible, making them immune to “tearing” effects.
Apart from that, we should also note that 32 GB of RAM is indeed an overkill in a gaming laptop, unless you also plan on using some memory-hungry professional software as well. If not, MSI sells several more affordable variants of this laptop, including versions with a GTX 1060 instead of a 1070, differing amounts of RAM, and different storage solutions.
When choosing a gaming mouse, you have a wide range of options to consider. For starters, do you want a wired or wireless connection to your PC? There are good wireless gaming mice available, including some with dual wireless/wired connectivity, but many serious gamers tend to prefer a wired connection for fear of a lag in response time or too short battery life. You will need to decide between optical or laser sensors for precision tracking, and whether or not you want an ergonomic design.
Of course, this is an entry-level gaming laptop and you should expect that some games have to be played on medium settings. However, you can expand this laptop later. For example, it has a second RAM slot for additional memory and an m.2 slot for a solid-state drive. Overall, this is a very good budget laptop with plenty of features at a great price point.
Dell is back in the market with their latest notebook in the form of Dell Inspiron 5575. This is an interesting variant from the Inspiron series of laptops from Dell, as it offers a very good set of specifications for the asking price. It sports a large 15.6-inch full HD display which is decent for gaming, and it is anti-glare so playing games for prolonged periods wouldn’t be stressful to your eyes. Moreover, it is fairly lightweight machine weighing just 4.8 pounds which is very good considering the kind of performance it offers.
Powered by a Skylake Intel Core i5-6200U processor with Hyper-Threading and 8GB of RAM, the HP 15-ay011nr will cope with everyday tasks and casual gaming with ease. The new Skylake series features the newer and more powerful Intel HD Graphics 520 chipset that will offer users similar performance to the GeForce 820M from NVIDIA. This means users will be able to run some newer gaming titles with acceptable frame rates on lower settings while older and classic titles will run on higher settings. The GPU relies on shared memory and while the 8GB of RAM is adequate, we recommend upgrading to 12GB or 16GB of RAM to maximize the performance.
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.
