Good news: It works. Small bezels make for an immersive experience. This will just have to do until we've got 4k VR goggles.
Bad news: It doesn't work great at native resolution. Even SLI 980 Ti cannot push 1.4 billion pixels per second in most modern games! But you CAN play most games at 3240x1080. Source Engine Games, and DX9 games like Rocket League can manage about 35 fps (~700 million pixels per second) , though, which is impressive.
Be sure to check out our reviews of the Korean 4k displays we've been enjoying. And remember: if you like the 34" ultrawides, these are the same width, only taller. :) If you've got room for a 34" 21:9 ultrawide, you've got room for a 40" 4k 16:9 because it's only taller.
