I don't have the space for a desktop PC, but I need power for games and video editing.
A fast processor and loads of memory are important, but the key to matching a tabletop computer is the GPU (graphics processing unit), which handles intensive video and 3-D effects. A number of brands feature this burly combo, but the best we've tested is the Asus ROG G751JT-WH71. It has a sprawling 17.3-inch display and a fast Intel Core i7 processor. The real engine, though, is the GPU, which pumps out smooth images whether you're playing Fallout 4 or editing action-cam video from your mountain-biking trip. [$1,199; store.asus.com]
