If the Dell G7 is unavailable, we recommend the very similar Dell G5 15 Gaming instead. It’s nearly identical to the G7, but the model we tested had a worse-looking screen with a greenish color tint, angled vents instead of rounded ones, and a red backlight on the keyboard instead of blue. Although we were able to test only the GTX 1050 Ti model, Dell confirmed to us that the G5 and G7 have identical thermal setups when configured with the same graphics card.
Many PC gamers rely on a high-tech gaming mouse for fast, precise aim in FPS and other games. These mice can also allow for more comfort than PC gaming controllers during extended game sessions, with less cramping in the hand and fingers, especially when paired with complementary gaming keyboards. And since a gamer mouse is, of course, a mouse, it can also perform double duty for everyday computing.
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.

The best gaming mice offer comfort and customization that will please a wide range of users, but in some cases, the core features of a mouse revolve around certain kinds of games. Blazing away in a firefight, staving off an advancing horde in a real-time strategy (RTS) title, or commanding an NFL franchise: Game genres have specific needs, and some mice outright target specific ones.
The keyboard is said to have quite a bit of flex, taking away from the VivoBook F510UA-AH51’s premium feel. ASUS have fitted the laptop with a 1920 X 1080 IPS NanoEdge display, which has an awesome 80 percent screen-to-body ratio. ASUS have cut some corners with the storage, opting for a slow 1TB 5400RPM HDD as opposed to an SSD. This is going to make applications and boot times rather slow and tedious sadly, but the other hardware does compensate for this.
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.
OriginPC - If you’re getting an Origin, it’s probably because you want customization options. The company offers a wide variety of paint jobs and skins and lets you choose from an array of different processors, GPUs and overclocking options. You can also get thermal compounds to keep things cool and you can even pick the exact RAM and storage you want.
Measuring 14.4 by 10.2 by 1 inches and weighing just 5.1 pounds, the Legion Y530 is one of the lightest and most compact gaming laptops we tested this year; it weighs more than a pound less than the Dell G7. The thin bezels surrounding the screen allow for a smaller laptop overall, and the Y530 is by far the most convenient model to slip into a bag and use on the go of all the options we considered. We also appreciate its all-black, understated design—no flashy colors, edgy angles, or ugly prints—and the comfortable matte-black material covering the palm rest.
Most people are familiar with the fact that many gaming laptops are not able to operate for very long on battery power due to their high-performance characteristics. In practical terms, computers such as the MSI GT75 Titan and the Asus ROG Zephyrus only have a battery autonomy of two to three hours…if at all! In fact, the measurements performed on these computers by the Laptopmag website were conducted using them to surf the internet via a WiFi connection. When these computers are used for gaming, their already low battery autonomy is further reduced (by half). Therefore, a connection to mains power is indispensable for these particular gaming laptops.
We also liked HP's updated battery optimization technology, which offered more than five hours of excellent performance on medium to high brightness. Best of all, this laptop is lightweight and slim. It's actually one of the lightest (4.68 lbs) and thinnest (0.6 inches) affordable gaming laptops we've seen! There's really a lot to like about this machine. It's powerful, light, slim, cheap, and looks great.
G-Sync or FreeSync: Several gaming laptops come with panels that support Nvidia's G-Sync or AMD's FreeSync technologies, both of which are designed to eliminate unsightly graphical tears and ghosting 0n monitors ranging from 1080p to 4K. While 60Hz is the current minimum refresh rate, there are an increasing number of monitors that offer 120Hz, which offers even faster rendering without introducing stutter. 
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.
