Last but not least, if you're a professional gamer looking to buy a gaming laptop that can keep you competitive, be prepared to brown-bag your lunches for a while. That kind of high-end performance can only come from top-of-the-line components, especially in a portable package, and they don't come cheap. Plus, an emerging trend among high-end machines is a high-refresh-rate screen built into the laptop, which allows for display of lofty frame rates in full to smooth out the perceived gameplay. Note, though, that you'll need a powerful graphics chip to leverage the benefits of a high-refresh panel with demanding games. You'll be able to identify machines like these by marketing lingo touting, say, a 120Hz or 144Hz screen. (A typical display on a laptop is a 60Hz panel.)
That said, there are still some basic conclusions to be drawn about graphics performance. In general, the higher the model number within a product line, the higher the 3D performance. So an Nvidia GeForce GTX 1080 generally produces higher frame rates and higher-quality graphics than an Nvidia GeForce GTX 1060 or GTX 1070. A single high-end discrete GPU will let you play the latest AAA gaming titles on a 1080p screen with all the bells and whistles turned on, and be fine for entry-level VR play. Adding a second GPU (a rare and expensive option) will let you run the latest games more comfortably on 4K and 5K displays, or let you hook up multiple monitors to your laptop.
In a gaming laptop, an SSD plus a hard drive is the best of both storage worlds. In terms of gaming performance, the storage subsystem affects game load times and in-game level changes. It can be of special importance in MMORPGs, where huge environments are loaded in real time. Thus, having at least some fast, SSD-based storage is desirable. To our eyes, you should only opt for an SSD boot drive at this point in time. The difference in performance "feel" between a hard drive and an SSD boot drive is too big to ignore. (See our picks for the fastest SSDs.)
The battery life of most gaming laptops should be ok when you arent gaming. I'm sure most of us understand this. For people who want to play games but also need a laptop for work or school, the batteries should last long enough. I'm assuming most if not all of them are set up so you can run them off the intagrated graphics until you need the dedicated for gaming or whatever.
For increased comfort, some gaming mice allow you to customize their actual bodies to your hand. Removable weights, often resembling small steel pills, are common in better gaming mice. Adding or removing these weights from slots inside the mouse body will shift the overall feel and the amount of drag. Some models take this even further, letting you adjust the center of balance, or change the height and pitch of the palm rest.
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
