Slim gaming notebooks have been getting a lot of attention lately as newer, more efficient technology allows manufacturers to cram high-end parts in a chassis that looks no different than a general-purpose notebook. The Maingear Pulse 15 falls right into this burgeoning segment packing a Core i7 CPU, 16GB of RAM, dual SSDs and a GeForce GTX 870M GPU in its a 0.7" thick body. Its standout feature is a 3K (2880 x 1620) display.
