+1.
GTX 560 Ti sees absolutely no improvement from having 2 Gb Vram. In any situation where that much Vram would really be needed (nothing which yet exists at 1920x1200), the GPU on this card would be too slow for it and you would need at least a pair of 3 Gb GTX 580s anyway.
People always want things that they dont need, and in this case wont provide even the slightest benefit. I'm yet to be limited by my SLI GTX 560 Tis in any game at 1920x1200 resolution and 4x MSAA.
In every benchmark except for BF3 in that review, the 2 x GTX 560 Ti significantly beats a single GTX 580, even at 2560x1600 resolution. That is what makes this card such an attractive SLI option - same, or even less cost than a GTX 580, more performance.
As for the BF3 results, I really cant tell what went wrong in that review, but heres how they actually perform:

Other people with two of these cards have reported a solid 60-100 FPS with Ultra settings, 2x MSAA, and far more with FXAA in BF3 (its still playable at 4x MSAA, but most people want at least 60 in FPS games).
Civ V is another game which has always been incredibly demanding ever since it was launched. People keep on blaming the coding or lack of optimization on it, but I'm running it without any hiccups at a constant 60 FPS (Vsync enabled with SLI ofc) and absolutely no lag, FPS spikes or any other problem other than waiting time in between turns (not a graphics problem - oh, and all settings on max and 4x MSAA).
Everyone that has bought a 1 Gb GTX 560 ti SLI setup on my recommendation so far have been nothing but thoroughly impressed by how great they perform. No one using this setup that I have yet seen have ever complained about lag spikes or microstutter in any recent and old video game.
Yet again, you are wrong about everything regarding SLI as usual.
