VRAM is not really an issue for me at 3x1680... but this may come in handy if (when) I upgrade my monitors.
Glad to see multiple manufacturers on this, too. (I mean, Gainward = Palit but both brands announced their own 3 GB card, right ?) Although I still fear the worse for local prices and availability.

Interesting, but can't really see how a 279% performance boost is possible at such a "low" resolution in Metro (meaning not triple head)
Sure, 2560x1600 is the pixel equivalent to low-res Surround 3840x1024. It is by no means a low resolution, though and every additional layer of filters and effects WILL weigh down on framerates. Plus since VRAM overload = slideshow, a 300% increase is not that surprising really... and is no guarantee for smooth gameplay, either. ;)
