When buying a gaming notebook, get one that will last you for a few years. If you can afford it, get at least an Nvidia GeForce GTX 1060 for basic VR support. That choice is more important than RAM and the CPU, though you should pay attention to those as well. Storage is the most likely to be upgradeable, but more is better, as games take up a lot of space. Decide if you prefer high resolutions or faster displays and consider what software will be helpful to you, but realize that you won’t get great battery life. How all of those work together determines just how well a gaming notebook does on the Tom’s Hardware test bench.
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.
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.
