Apologies for this being only tangentially on-topic, but has anyone got a recommendation for a decent video card for driving a 4K monitor under Linux? The audio connection here is that I'm looking for something that is passively cooled (or at very quiet if not), performs well, and is low-latency friendly (so probably not proprietary drivers)? With those requirements I don't really fancy my chances in the "google, buy and hope" approach. I've been using cheap nvidias with nouveau for a while but performance of certain operations (scrolling, dragging/resizing windows) is painfully slow, particularly since I made the jump to a 4K monitor. Has anyone got some success stories? bjb
