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.
Minimal Portability (17 - 18 inches): If you plan to keep your laptop in your home and leave it on your desk or just move it between rooms, a system with a 17 or 18-inch display like the Alienware 17 should be fine. Laptops in this size range are usually the most powerful, because they have plenty of room for heat-generating components. However, they're heavy to carry, a tough fit for most bags and too power-hungry to use unplugged for very long.
Processors are the next biggest difference. You'll likely get a capable Core i5 instead of a faster Core i7. Still, some of the benefits of an i7 machine aren't a major factor for gaming, but instead benefit video editing and other creative uses, so an i5 will do the job. The newest generation of these chips are fast and efficient at a base level, and won't be too much of a bottleneck for gaming. On the AMD side of the fence, in the rare gaming laptops you'll find based wholly on AMD core technology, gamers will see mostly graphics solutions based on the now-aging Radeon RX 560, RX 570, and RX 580 paired with one of several AMD FX or Ryzen CPUs. Outside of the graphics card and processor, the other components should actually be closer to more expensive machines than you'd expect.
The laptop comes with a long list of ports and also has a good heat exhaust system, making it a perfect choice for gamers and all other hardcore users. As far as the graphics on the laptop are concerned, it comes with the Intel UHD 620 integrated graphics. All in all, the laptop offers an excellent set of specifications for a little above $500, but considering the design and performance of this laptop, we think it’s worth it.
Gigabyte/Aorus - Gigabyte and its high-end subsidiary Aorus offer a diverse lineup of gaming systems. Where Aorus laptops are svelte, lightweight powerhouses with high-end specs while Gigabyte systems tend to be bulkier, more colorful and less expensive. All Aorus laptops and selected Gigabyte systems have two-year limited warranties while the remaining systems only come with 1 year.
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.
And thanks to Nvidia's 1050 Ti GPUs, you can hook up an Oculus Rift and jump into the virtual realm.  However, some companies like Dell and Gigabyte are outfitting their rigs with Nvidia GTX 1060 Max-Q GPUs so fans of the HTC Vive can also get in on the fun. Or if you're not ready to make such a big financial or space commitment, you can hook up one of Microsoft's new MR headsets like the Acer Windows Mixed Reality AH101 headset, which has the added bonus of working with either discrete or integrated graphics. Best of all, you can use all that money you just saved to splurge on a top-notching gaming keyboard or mouse.
