Doom
Absurdly violent and increasingly gruesome at every turn. It's fast, it's frantic, it's Doom. A game that needs no introduction to PC enthusiasts, this 2016 reboot brings hell's evil forces to life with updated visuals and is without a doubt one of the most eagerly anticipated launches in years.
Doom is well-coded enough not to require a beefy GPU at anything other than 4K, but it's nice to have a silky experience on an ultra HD screen.
