OLED: Described as the future of display, an OLED (organic light-emitting diode) panel is comprised of a film of organic compounds that produce light when an electric current is introduced. The technology allows for thinner, more power-efficient panels that deliver incredibly rich color and contrast. The Alienware 13 R3 OLED is currently the only laptop to feature this technology.
Next in the low-cost gaming segment is the Dell G3 Series 15. It's currently on sale for $699 making it one of the lowest cost gaming notebooks. The $699 price also gives you a choice between a 1 TB HDD model, or a 256 GB SSD version, which lets you choose based on how large your gaming library is, whether to take a slower spinning drive with plenty of space, or a SSD for better system performance all the time, but you may have to add space later. The G3 Series 15 can be had with a Core i5-8300H on the base, or up to a Core i7-8750H. A Geforce GTX 1050 is the opening GPU, and Dell offers a GTX 1050 Ti on the higher end configurations. The display is a 1920x1080 IPS, and although it's not the best display around, the GTX 1050 should be able to drive it while gaming at reasonable frame rates.
The G7’s 60 Hz 1920×1080 IPS display was neither the best we tested nor the worst. It made games look good, and the G7’s display looked noticeably better than the G5’s and G3’s screens, which both had a sickly greenish tint. We found that the G7’s screen couldn’t get as bright as those of the other budget gaming laptops we tested, maxing out at 228 nits compared with the Lenovo Y530’s 266 nits and the Asus TUF Gaming FX504GM’s above-average 317 nits. And although it’s not a requirement, we’d love to see a higher-refresh-rate panel available on the Dell G7, since that would make first-person games smoother and more enjoyable.
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.
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.
