Last time I checked you could have crossfire or Eyefinity but not both. They may have fixed that with the last driver release. The last driver allowed bezel correction and I was more focused on that part. If you want the option to run in portrait mode get IPS LCD panels since you'll need the wider viewing angles. Dell has IPS displayport monitors. If you set your field of view to 140 in AH the horizontal middle third of your current monitor is what you see with 3 monitors in landscape mode, assuming the same aspect ratio monitors as your current monitor. In portrait mode it will be what you have now, but in both cases it will be much bigger and higher resolution. Bigger is better. I have gotten used to the reduced vertical view angle in landscape mode. I would hate to go back to one monitor. If Crossfire supports Eyefinity go for it. If not there is always the 5970.
