So is there any advantage of using a 3 monitor setup over using one single big high res monitor? I'll be in the market for a monitor upgrade in the next couple of months, so I'm looking to educate myself.
Well I'm running an eyefinity card, and I knew about the field of view really. I probably should have been more clear in my question I suppose. Would I be better off in game to have a much larger single monitor from an overall resolution standpoint or with the three monitor rig, notwithstanding the obvious differences in field of view. Does the wider field of view also mean lower resolution overall? Which will allow me to see details better at a distance and in a fight? Do the bezels have much over effect on your view? That sort of thing.
When you say large, do you mean Something like a 30", 2560 x 1600 Dell display?
http://www.overclockers.co.uk/showproduct.php?prodid=MO-023-DE&groupid=17&catid=1120&subcat=Large IPS displays suffer from poor pixel response rate/ghosting, this makes them terrible for gaming, especially Aces High 2! They are built for professional use, photo editing/cad work. I suggest you stick to the faster 1920x1080, TN panel, 24" displays.
Having three displays in eyefinity will not reduce the resolution. Think of it like this, you're just gaining 2 additional displays beside your main display. For example: 1920 x 1080 x 3 = 5670x1080.
You'll not notice the bezels after 10 seconds of use, you can even stack the bezels behind the centre display for even more of a reduced effect. Backlit LED monitors do this really well as they're ultra thin.
Now if you're really minted, you should look at the new 120hz displays which will be flooding the market soon.
