When I first got the RTX 4090 in 2022, I paired it with a 4K/160Hz IPS monitor because I knew it was powerful enough to handle almost any game I threw at it. Moreover, at that resolution, the GPU is usually the limiting factor, so I didn’t have to worry about any other bottlenecks in my build. A couple of years later, though, I wanted a faster monitor purely for competitive gaming, so I got the Alienware AW2725DF 360Hz OLED.
