For increased comfort, some gaming mice allow you to customize their actual bodies to your hand. Removable weights, often resembling small steel pills, are common in better gaming mice. Adding or removing these weights from slots inside the mouse body will shift the overall feel and the amount of drag. Some models take this even further, letting you adjust the center of balance, or change the height and pitch of the palm rest.
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.
Because they usually require dual GPUs for the smoothest gameplay at native resolution, 4K gaming laptops are still the exception, and still expensive. And keep this in mind: Only the most powerful graphics cards can render complex game animations at playable frame rates across the full screen at 4K, so a 1080p screen may actually be a better use of your money if all you do is play games.
Computers in the GT series are very high-end; they are also exceedingly expensive, large, and heavy. Some of the computers in this series distinguish themselves from the competition by their mechanical keyboard and the very high quality of their display (120 Hz G-Sync compatible, for example – see LaptopMag’s test of the GT75 Titan). The MSI GT83 Titan features an enormous 18.4-inch display in addition to dual GeForce GTX 1080 graphics chips connected via SLI.
That said, notebooks aren't upgradable, apart from their primary system memory (RAM, not to be confused with the graphics memory) and in some cases, the storage. You're going to be stuck with the screen, the graphics chip, and the processor you buy now, so evaluate these parts wisely. If you can stretch your budget a bit to get the next-tier-higher component, it can pay dividends in terms of usable life.
Of course, the more a computer’s components heat up, the faster its fans will turn and the more noise it will generate. If you prefer to wear headphones when gaming this increased noise should not be much of a problem. However, if your computer’s temperature increases too much, a throttling mechanism will activate, reducing its CPU and GPU frequencies in order to protect them; this will reduce your computer’s performance in the process. This is one of the aspects that we pay the most attention to during our testing of gaming laptops.
The 256GB M.2 SSD is slightly small, and it is bound to fill up soon if you have large game library, but it is blazing fast, meaning your load and boot up times will be quick. The battery life is disappointing, however, running out of juice after about 3 hours of heavy use. You will need to remain plugged in most of the time, but this shouldn’t come at much of a surprise considering its energy-sapping components.
GPU or the graphics processing unit is considered to be the most vital part of the gaming laptops. This chip is doing the hard work, thereby providing you the eye candy. It is recommended to choose a laptop with a powerful GPU for running the most demanding games. The GTX 760M or Geforce GTX 850M happens to be the least requirement for those gaming laptops. You can also go for the laptop with GPU of 800 or GeForce GTX 700 series as they are recommended for the games of today.
Starting at $699, it's going to be hard to find a more affordable gaming laptop than the Asus TUF Gaming FX504. For the price, you get an 8th Gen Core i5 CPU and a Nvidia GTX 1050 GPU, which is enough to play most games on low or medium settings. Keep in mind that such a low price point, means that some sacrifices must be made. But if you want to spend as little money as possible for a gaming rig, the FX504 is the way to go.
