This isn't true, in Battlefield 3 you can see alot more of the battlefield around you and this helps especially as a sniper, as it means you can look between your monitors to spot more enemies without having to spin your character around as much and giving your position away with movement in the bushes.
Anyway back to the original poster...
VRAM is definitely the master villain you have to watch out for in multi screen gaming, the more you can get the better, however there is the misconception that if you have 3 screens you have to have to game at 5760x1080/1200 or nothing.
3840x720 (which is basically 720p HDx3) allows you to play comfortably in multi screen gaming with most games at max settings and VRAM becomes a lot less of an issue. And I can tell you that even this resolution is so much better than single screen gaming at 1080p, the immersion makes gaming ...well 3 times better atleast.
Only extreme cards such as the GTX 580 3gb's in upto tri-sli or even quad sli can handle any game comfortably with max settings at resolutions of 5760x1080 and above on demanding games.
Crysis, Crysis 2 & Metro have been reported; on this forum; needing upto 2.7gb of VRAM at these settings, the 6990 only has 2gb of VRAM and GTX 590 only has 1.5gb of VRAM, even if they advertise as having double that.
With your 16:10 monitors you posted in your OP you could game at 3840x800 and get the same results.
So nearly all of us with Eyefinity or Surround Gaming are making compromises here and there to play games the way they should be played Edited by Chobbit - 10/19/11 at 2:07am
