The green team has got their problems too, I read somewhere that several people are getting lag issues on the the HDMI monitor. I think the only solution is to have both a nvidia and an amd card and have the best of both worlds xD
Problem like this
http://www.youtube.com/watch?v=Ymw6D2iB-1Y also happens on the red team but they address little problems like this. On the green side though they don't seem to support a product for very long time on the Surround field...
I'm very sensitive to tearing, specially horizontal lines on sim racing (I would love to have 120Hz G-Sync on a triple screen, that would be a perfect experience, but it doesn't even exists drivers for that, yet. And I don't have 1500$ laying around just to play a game (lol))
DVI + DVI + Active DP Adapter, most probably it will cause tearing so the 3x DP outputs + same adapters seems to be the best eyefinity solution, right? (They're not expensive taking in consideration AMD is a lot cheaper than nvidia

With two nvidia cards I can use all three DVI outputs without DP, and that's a good bonus
But Surround + SLI... just sounds UNSTABLE to me...
Maybe I'll buy a single nvidia (2dvi+hdmi) and see it for my self, if I run in to tearing problems I simply return it and get an AMD card.
ps. I can get a new Asus Radeon R9 290 4GB GDDR5 by 350€ on my country
