I like having a 4k monitor with a somewhat underpowered video card for the task. Most games that are graphically intense let you set the 3D render scale to something lower. At 70% render scale I get the benefit of sharp 4K text and UI stuff but with the 3D parts being closer to 1440p resolution. Upscaling can be really ugly at lower pixel densities, but rendering 1440p scale on 4K is hardly distinguishable from 1440p native, in my experience.
