2GB doesn't help scaling unless the game runs out of memory with 1GB. Of course nothing's preventing Nvidia to improve SLI scaling with their drivers like AMD did.
I don't see much reason for buying a 2GB version of GTX 560 unless going crossfire and triple monitor. Probably the only reason they make a 2 GB version is because 6950 has one.

It does look a bit bad that the lower end card has 2GB whereas 570 and 580 have less.
But in the end it's good that there's a card for everyone. Let's just hope GTX 560 will bring in some more competition and lower prices.
