Multimonitor with FXAA on 2GB is definitely fine unless you have hi-rez texture mods up the wazoo or something.
Multimonitor with MSAA, though, is iffy. at 5760x1200 you already run into memory issues at BF3 with 2x MSAA and 2GB, according to HardOCP. (Some people have been running around the boards proclaiming 2GB as enough for 5760x1200 based on the HardOCP review, but they didn't actually read the review and how they said they were forced into FXAA because MSAA was proving too much for 2GB VRAM to handle.) And you can forget about 4x MSAA. http://www.hardocp.com/article/2012/04/25/geforce_gtx_680_3way_sli_radeon_7970_trifire_review/4 The 7970 had suttering issues with MSAA but that could be due to CF/driver issues, and in any case the point is that 2GB VRAM might not be enough with 2x MSAA or higher, on some games at 5760x1200.
On the other hand if you are running 3x2560x1440 (a resolution I may step up to in the near future) you will need more than 2GB VRAM if you want any breathing room for present and future games; that resolution is equal to 5.3 1080p panels!
Personally I favor MSAA over FXAA but if you don't, or you don't care about ANY AA, then 2GB is enough for now.
