Great article, Steven! This was precisely the kind of inquiry I was hoping to find right now.
Currently, I'm very interested in running a three-monitor gaming setup (really just to see what all the fuss is about) with 3 displays at 1920x1080 each, which I believe in landscape mode will put me at about 5760x1080?
The question I was very interested in was whether a single high-powered dual-gpu card such as the ones you tested in this article would be able to play popular titles at smooth frame rates. For my own needs, I probably wouldn't need more than medium or high settings, so I'm guessing right now that it is a very doable thing.
