I admit I don't pay much attention what's current in PC hardware so had no idea that running 4k is that demanding still. Myself I don't even have a dedicated PC screen, my rig is in the living room hooked up to my HDTV. As such all I need is 1080p @ 60Hz, which you certainly don't need to reach for the top shelf for. I've a GTX670 in it now which still runs just about everything fine. Elite: Dangerous does lag a bit sometimes though, so I've been thinking about upgrading. But really, I should build a new rig as this one is close to six years old and the mobo, CPU and PSU in it has never been changed.
