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.
At the mid-range we see laptops with either the NVIDIA GTX 1060, or for a bit more money, a GTX 1070, both of which are a powerful gaming GPU in a mobile form factor. ASUS offers the Republic of Gamers branding Strix lineup, and the GL504 model is their 15.6-inch range. Featuring the GTX 1060 in the GL504GM, and GTX 1070 in the GL504GS models, there's a wide range of performance here depending on budget. ASUS offers either the Intel Core i5-8300H quad-core, or the Core i7-8750H hex-core CPU, and up to 32 GB of DDR4 RAM support. There's a full range of SSD choices, and you can of course also fit it with a HDD for extra space.
The SteelSeries Rival is a very solid mouse, but it's also very specialized: I have a feeling if you need this mouse, you know about it already. The key feature of the Rival 500 is the sheer amount of programmable buttons this thing has. With 15 different buttons in tow, it's basically a keyboard replacement! This is a setup that's ideal for games with lots of macros of cooldown skills—think MMOs or even MOBAs.
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.
