2x 2gb gtx 670 vs EVGA gtx 670 sc 4gb?

There isn't any games that will require 4GB of Vram. To have that much you would have to have many monitors and run in very high resolution like 2560 x 1600 to get the use of the Vram.

If you want to run 60fps on everything then just start with the card you have and if you are not getting what you want then either get another 670 2 gb of Vram or get a 680 but of course send back the 670.

You try with what you have then it goes up from there. I hope this has help a little and good luck to you and those cards are very nice I think you will be impressed and it should handle any game thrown at it.

Yeah, VRAM shouldn't be an issue if you stay on 1920x1080.

There´s no difference, if you search for the benchmarks there is barely a 3 or 4% difference from 2gb´s to 4gb in the 680´s plus those special cards are pricey.

VRAM does not add up when you SLI - just because you have 2 sets of 2GB 670's , the total VRAM will not be 4GB, it will stay as 2GB. As for METRO 2033, - the GTX 670 is benchmarked at about 50+ FPS average.

Stay with your setup, the extra card will yield better performance but with a single monitor, you don't need to worry about VRAM.
