Nah. 4K gaming laptops are overkill; they're fine for video editing if you're dealing with 4K content, but it's not the optimal choice for games. The standard 1080p resolution means that the generally slower mobile GPUs are all but guaranteed high frame rates, while companies are slowly drip-feeding 1440p panels into their laptop ranges.
A 1440p screen offers the perfect compromise between high resolution and decent gaming performance. At the same time, a 4K notebook will overstress your GPU and tax your eyeballs as you squint at your 15-inch display.
