I hate ro break it to you but this monitor won't work with any current nVidia GPUs. For some reason they have stuck with Diaplayport 1.4a, and to drive that resolution requires 2.1. This means to use this monitor you have to go with AMD!
BTW, regarding the screen panel technoloy, it's urilising microdots the same as Samsung's high end TV panels. Many dismissed that technology compared to OLED, but once those TVs were released they blow LGs OLED screens away for depth of colour and screen brightness when the room is bright. So I suspect this monitor will look amazing.
BTW, yes I am perfectly happy gaming at 60fps. My interest in this monitor is from graphic design, video editing and post production motion graphics. For that I would be utilising 120fps for video.
