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 you want AAA performance and have a little money to spend, consider the (now previous-gen) $1,800 Razer Blade, which brings the literal heat — as in, consider a cooling pad. With an Intel Core i7-7700HQ and 16GB of RAM, and at just over 4 pounds, it's less than half the weight of the Alienware 17 R5. The downside: Razer's unsubtle snake logo screams, "I'm not doing work!"
If the refresh rate (which is measured in hertz, or Hz) is being called out as a feature on a given laptop, that means it's likely higher than the norm. Most laptop screens, including those in almost all budget models, stick to 60Hz, which means they redraw the onscreen image 60 times per second and thus can display up to 60 frames per second (fps) of in-game performance. (If your graphics chip can produce 90fps in a given game, you'll see only 60 of them.) Some notebook screens these days, though, can display at 75Hz, 120Hz, or more. These high refresh rates can be beneficial for some extremely fast-paced games, particularly titles played competitively online, such as Counterstrike: Global Offensive, DOTA 2, and Overwatch.
The all new Razer Blade was relaunched this year as a 15-inch model, replacing the outgoing 14-inch version with a new thin-bezel design that is stunning. Razer has always offered one of the best looking gaming laptops around, featuring a fully CNC machined aluminun chassis, and a lot of performance in a thin and light form factor. The latest Razer Blade 15 is powered by a Core i7-8750H hex-core CPU and a GTX 1060 Max-Q GPU. The lowest cost configuration comes with a 128 GB SSD and 1 TB HDD, and you can go up from there. Currently it is available for $1600 with a 1920x1080 60 Hz display, and Razer has configurations with 144 Hz displays, as well as models bumping the GPU up to a GTX 1070 and a UHD display. There's also a limited edition Mercurty White color option on certain configuraitons.
Although priced slightly higher than $500, the Aspire E 15 E5-575G-57D4 has earned our top pick in the budget gaming category thanks to its dedicated NVIDIA GeForce 940MX graphics card which offers more than twice the performance of competing laptops with only integrated graphics units. The Aspire E 15 will run titles such as Overwatch, Battlefield 1 and Titanfall 2 on low to medium settings with graphics performance more than double than competing integrated graphics based laptops below.
In addition to poring over our reviews and checking out the vendors' sites, using the price filters at a reseller like Newegg.com can help you see different configurations at different price points. Some manufacturers offer lots of differently weighted versions of the same laptop (say, more storage in one config, a better GPU in another). Playing with the filters on these sites can be an illuminating exercise in give-and-take.
Ever since the 2016 launch of mobile Pascal, gaming notebooks have mostly closed the gap with their equivalent desktop cousins. With Nvidia's previous-generation "Maxwell" architecture, mobile-graphics-chip performance tended to be roughly 70 to 80 percent of what you'd get from the desktop cards they were based on. (See our picks for the top gaming graphics cards for 1080p play.) But the Pascal mobile chips deliver almost equivalent performance to their desktop counterparts of the same name, assuming they are implemented in machines with a complementary CPU, and in designs that do the GPU's thermal needs justice. (Most do.)
After picking our hardware criteria (see above), we scoured the websites of major gaming-laptop manufacturers like Alienware, MSI, Asus, Razer, Samsung, Acer, HP, and Lenovo, and we browsed boutiques like Xotic PC, iBuyPower, Clevo, iBuypower, Origin PC, Digital Storm, and others. Then we put together a list of the laptops that fit our requirements and have positive reviews from trusted sources like CNET, AnandTech, Engadget, Laptop Mag, PCMag, and Notebookcheck, and eliminated those that didn’t.
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.
IMO the Roccat Kone is a great mouse. Comes with weights to make it heavier if you don’t like how it feels, the XTD version comes with OLED strips on it that are customisable to 4 different colours (two on each strip one top one bottom on both sides that blend together in the middle) and they have just released the LEADR which is the wireless version.
