Nailing down a high-quality mouse sensor is tricky without getting hands-on time with a given mouse. The two key sensor types are "optical" and "laser" sensors, but you can't apply absolutes when judging them. Your best bet is to try out a mouse in person, or to rely on formal reviews like ours, as well as online forums, for the skinny on how a mouse feels in specific play situations.
As with every product that we review, we put these PC peripherals through their paces with lots of real-world testing. In other words, we locked ourselves away in a cool, dark room with a sufficient supply of snacks and caffeine drinks and played all kinds of games – strategy, FPS, RPG and beyond – until our fingers were little more than withered stumps.

Avram Piltch is Tom's Hardware's editor-in-chief. When he's not playing with the latest gadgets at work or putting on VR helmets at trade shows, you'll find him rooting his phone, taking apart his PC or coding plugins. With his technical knowledge and passion for testing, Avram developed many real-world benchmarks, including our laptop battery test.
But of course, the same advantage goes for gaming laptops as it does for every laptop, and it’s portability. What they lack in regards to raw power, they make up for by balancing power and portability extremely well, so if you need a gaming computer that you can easily carry around with you wherever you go, then a gaming laptop is still definitely worth the money.
Being the fastest mobile graphics adapter, Nvidia’s GeForce GTX 1080 combined with Intel Core i7-7820HK shows astonishing performances at 1080p. The 100 FPS was easily achieved for many games, and even the heaviest games succeeded 60 FPS at 1080p. For certainly, this is one of the fastest gaming laptops, and the GTX 1080 makes sure of experiencing the same satisfaction as using a top-class desktop.

Ever since the 2016 launch of mobile Pascal, gaming notebooks have mostly closed the gap with their equivalent desktop cousins. With Nvidia's previous-generation "Maxwell" architecture, mobile-graphics-chip performance tended to be roughly 70 to 80 percent of what you'd get from the desktop cards they were based on. (See our picks for the top gaming graphics cards for 1080p play.) But the Pascal mobile chips deliver almost equivalent performance to their desktop counterparts of the same name, assuming they are implemented in machines with a complementary CPU, and in designs that do the GPU's thermal needs justice. (Most do.)
Before we begin looking at just how good the Steel Series Rival 700, there are some obvious things you should know about this mouse; the Rival 700 is unique in a sense that it carries an OLED display that can display a variety of different things including settings, as well as some GIFs that are specifically made for this display and can be downloaded from several series.
You can be disappointed if you presumed that Kaby Lake made big improvements. While benchmarking the new chip of Kaby Lake has shown nothing breathtaking. The next in line Skylake, packed with the same clocks, runs ahead by a mere couple of percentages. Showing speed improvement of 3%, the Core i7-7820HK is only a bit faster that Core i7-6820HK, which is shown when conducting Cinebench R15 and Cinebench R11.5 at 4.0 GHz
All the way thru our review and usage, we never noticed eve a bit dim on the ASUS FX502VM display. Bright, filled with color, alive vivid look and wide angle viewing display is a rare feature. On our light meter during benchmarking, ASUS’s notebook detected an average brightness of 289 nits, which for a laptop from this class is an awesome leap from the others of the same class.
The Predator Helios 300 boasts a rather aggressive exterior, replete with red highlights and conspicuous geometric details. And much like the MSI GV62, the keyboard comes with a red LED backlight. This clearly establishes its identity as a gaming laptop at the very first glance, though what’s under the hood doesn’t disappoint either – and we should hope so, considering the price tag.
As far as the gaming performance of this laptop is concerned, the HP 15-ay191ms comes with the 7th Generation Intel Core i3 processor paired with the 8GB of RAM and 1TB of hard drive for storage. Thanks to the integrated Intel HD graphics this laptop can run some of the popular older games at low to medium graphics settings. Moreover, the audio on this laptop is powered by DTS Studio Sound which makes watching movies and gaming on this laptop more immersive.
