video editing????????????Ya right, you do realize most video editing apps save for a couple use very little graphics power at all, most of them use sheer CPU power, which makes sense, a video is nothing more than a stack of images multiplexed with sound.HDTV video resolution for NTSC is 1440x1080 or less, and its not even mainstream yet, DVD's are 720x480 in NTSC, not much need for GPU power there.
That card supports resolutions up to like 3800x2400, its for doing 3D models and hires graphics design, raytracing, and other super fine graphics work.You'll find equipment like that in places where engineers design parts for cars,planes,buildings, and machines in 3D using CAD.Might find a few like that in a handful of companies that make 3D models for games on occasion, but not at that resolution.A few operations that do virtual reality type work probably use them on occasion to make models.
