Gaming systems have higher-end components than run-of-the-mill consumer laptops, so their prices will be consequently higher, but the range across the category is huge: from under a grand to $5,000 and up. The best budget gaming laptops start at $800 and can go up to about $1,250. For that, you get a system that can play games at 1,366-by-768 resolution on high graphics quality settings, or at a full HD (1080p) resolution with the details turned down some. Storage may be a hard drive, or a modest-capacity solid-state drive (SSD).
To muddy the waters, Nvidia in 2017 introduced a technology called Max-Q Design that squeezes a slightly detuned GeForce chip into thinner and lighter notebooks than would normally be possible, at the expense of 10 to 15 percent of the chip's performance. Because Max-Q tends to be implemented in thin, premium machines, it's seldom a factor among the under-$1,000 brigade, but it's good to know what it is, in case you encounter the term when shopping. (A few models just above the one-grand line incorporate the tech.) You may be interested in a Max-Q rig if maximum portability—not a trait usually associated with gaming laptops—matters to you.
If you're looking for a cheap gaming laptop to buy, the Ideapad Y700 should be at the very top of your list. It has an amazing price-to-performance balance, one of the best of all budget laptops we've found. The Ideapad features the very fast Intel Core i7-6700HQ at 2.6 GHz, which clocks in at over 10,000 points on Geekbench. This ensures that you have plenty of CPU power to multi-task and play games on high settings. The CPU is cleverly paired with the popular NVIDIA GeForce 960M. It's currently the best mobile graphics card for people on a budget.
More the issue is knowing how your mouse connects to its host. The three main possibilities are USB (via a typical cable), USB (wirelessly, via an RF USB dongle), or Bluetooth (also wireless, usually via the host's built-in Bluetooth radio). Bluetooth is the least common of the three in gaming mice; it tends to be found more often in productivity or mobile mice. Note that some wireless models with rechargeable batteries come with a USB charging cable that can double as a mouse cable while you're juicing back up, letting you continue using the mouse with the battery depleted.
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.
For a high-end system, we recommend 16GB, so you can have more than one gaming session, your messaging app, several websites, a webcam program, and your video streaming program open simultaneously. A midrange gaming laptop should function fine with 8GB of memory, but be aware that many new laptops are not upgradable. You may be stuck with the amount of memory you order.
