The 4K display will utterly kill any attempt at gaming and is incredibly pointless in a laptop - the screen is just too small for it to matter, 4k is meant for massive displays (typically a 4K gaming machine will use one and often two extremely powerful GPUs like GTX 980TI or 1080 just to pull 60 FpS). The graphics on that are trash and will barely be able to run minecraft without any shaders, resource packs or graphical enhancements.
