Well, I do a lot of video editing, so fanless cards are really not an option for me, because their performance is abysmal (and yet perfectly competent for DAW use.)
Yes, I know about the 4k requirements, what I was trying to say is that for the purpose of running a DAW with as many pixels as possible (i.e. enlarged workspace), a 3-screen setup like mine is still the most practical solution, and one that wouldn’t require super-expensive hardware (you can still have a 3-screen setup even with a cheap GPU, although you will definitely need more than one.) I don’t spread the sequencer page over multiple screens, I actually only use the central screen for that, the right screen for the mixer and the left screen for VST management. So the bezel thing is really not an issue for me.
