More the issue is knowing how your mouse connects to its host. The three main possibilities are USB (via a typical cable), USB (wirelessly, via an RF USB dongle), or Bluetooth (also wireless, usually via the host's built-in Bluetooth radio). Bluetooth is the least common of the three in gaming mice; it tends to be found more often in productivity or mobile mice. Note that some wireless models with rechargeable batteries come with a USB charging cable that can double as a mouse cable while you're juicing back up, letting you continue using the mouse with the battery depleted.
The second comparison. Is the gaming laptop build with plastic, metal or a combination of the two. This will impact the durability, the weight and look of the laptop. Budget gaming laptop are usually built with a combination of the plastic and metal, usually metal on top and plastic at the bottom. It’s also up to you to know what you want, because every laptops build quality will be a little different.
Purists will argue that you need a PC to truly play games, especially if you're a fan of pushing the levels of graphics quality beyond the capabilities of a mobile phone or a mere gaming console. In this regard, the gaming desktop is still king, particularly when it comes to having the kind of components and horsepower needed to run 4K games smoothly and support virtual reality (VR) setups, such as the Oculus Rift and the HTC Vive. But if you want or need something you can tote around the house or over to your friend's place, we're here to help you choose the right gaming laptop.
Though, as with most budget laptops, you will get a slower 5400rpm hard drive. However, seeing as more and more of us are moving over to digital copies of our games it makes sense to remove the DVD drive and replace it with a HDD caddy and a good SDD. This will allow you to reap all the major benefits that an SSD offers for gaming and day-to-day use.
Heat: A gaming laptop’s GPU and CPU produce a lot of heat. Without an effective cooling system, the machine will overheat, which can slow gaming performance, shorten the laptop’s lifespan, or even burn you.1 No gaming laptop can keep completely cool—all that heat has to go somewhere. But it needs to keep its internals, the WASD keys (the most-used section of the keyboard for gamers, as those four keys often control in-game movement), and the left palm rest (where your left hand rests while using the WASD keys) cool. It’s a bit more forgivable for the laptop to get hot in areas with less direct contact with your skin, such as the underside and the strip above the keyboard.
VR and the Highest Settings: A GTX 1070 will let you play through just about anything on high settings, while the GTX 1080 is the most powerful card out there for laptops right now and will allow for smoother VR and special effects. These are the cards that will let you start pumping up effects like Nvidia Gameworks. Laptops in this range can start in the high $1,000 dollar range, and, depending on what other specs you need, go over $3,000.
