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.
While the Pulsefire FPS's lightweight design is probably great for FPS titles specifically, I prefer a little more weight with my mice, and it felt a bit loose/jittery during a title like StarCraft. Then again, if you're primarily looking for an FPS-focused mouse, the Pulsefire is one of the best options I tested. Just don't expect it to be as good for games across multiple genres.
$2,000 - $3,000: When you're spending this kind of money, you'll definitely get a quad-core Intel Core i7 processor with at least 16GB of RAM. You'll find configurations with the new PCIe SSDs for lightning-fast game installs and loads. Screen-resolution options include 1920 x 1080, 2560 x 1400 and 3840 x 2160. Regarding graphics, you can get a laptop with a single 1080 or dual 1070M in SLI configuration. You can also snag one of the new lightweight Max-Q laptops at this price range. Ultra smultra, with these kinds of specs you can play any game at the highest settings without fear of lag or ugly tearing.
Although the E15 comes with a Full-HD IPS display, some have noted that it is fairly dim compared to higher end displays. Regardless, you will get decent viewing angles and the matte finish will prevent any potential glare. It has a solid battery life of around 8 hours and 30 minutes,  with Acer even claiming up to 15 hours of battery life, though heavier applications and games will drain its battery life a lot faster. The NVIDIA GeForce MX150 is by no means a beast compared to higher end cards, and most modern AAA titles will struggle somewhat, but lowering the graphics will afford you some playability even on next-gen titles.

Even if you're not familiar with Logitech's standard gaming mouse filigree, the G502 is very intuitive. It features two center/top buttons, one for toggling the mouse wheel between "loose" and "granular" settings, and one for adjusting DPI presets on the fly. This is the case for most Logitech mice, but it's nice to get both options on such an affordable product, and one that also features multiple tunable buttons. The G502 also uses a handy LED-based DPI indicator for various settings—normal, fast, super-fast, and slow—so it's especially good for shooter scenarios where different weapons call for different optimal speeds.
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.
