If you buy a single GTX 1080 you should be able to get good results on a 4 k screen . It will take messing with settings in each individual title to get the best results . For instance , you could probably run Star Wars Battlefront at Ultra , then use the resolution scaler to set it at 85 % of 4 k and get great results . Other games do not have as much settings tuning ability as that title , and if you had to settle for 1440 p on a 4 k screen it wouldn ' t look bad in motion , but it would look , well , not crisp . If I were you and I wanted a 4 k screen but had only the budget for a 1080 I would target 4 k for every game , and lower settings until I got 60 fps . Some titles you won ' t have to lower settings much , others will be a lot . It ' ll take time and experimentation on each title to get the best results , which may not be worth it to you .
