Not sure about any new tech like Eyefinity until I've seen it in action, but I've been using dual DVI out into 2 1920x1200 displays for years. I also use Synergy to span the keyboard and mouse onto a laptop to the right and left for admin related tasks. It seems harder to find the 1200 vertical pixel displays than it should be... the trend seems to be for 1920x1080p, despite the fact that there's more screen real estate with the 1200!
