Same thing as above, if you are gaming at 1080p(1920x1080) or below, the SLI setup would probably out-perform a 670 or above. If you are gaming at higher resolutions than that(or might in the future) going up to 2GB or 3GB of RAM on the newer cards is going to be a huge improvement over dual-1GB cards.
I personally upgraded from dual-4870s with 1GB apiece on them to a 3GB 660Ti. The 1GB on each card was bottlenecking me just a bit at 1920x1200, I regularly see my video card RAM bump up to 1200+ MB used when watching the sensors on GPU-Z.http://www.techpowerup.com/gpuz/. 3GB is definitely overkill for my 1920x1200, 2GB would perform just the same since I'm not even ever using the full 2GB, but I plan on going up to a 2560x1440 monitor soon.
I'd recommend downloading that utility, play your favorite game in whatever resolution you use, and see if your RAM is getting maxed with your current card, because a 2nd card won't help that at all.
