I have a 2GB Nvidia GTX 670 at the moment. Its great but I want to boost my video memory up to 3 GB. Is it possible if I bought a cheaper 1GB card and used them both at the same time?

SLI doesn't work that way. 2GB + 1GB = 1GB. SLI will use the lowest VRAM available. Chances are, you're playing at a resolution that doesn't even require 3GB of VRAM, and you would likely benefit from a stronger card than 3GB of VRAM (although the cards that come with 3GB of VRAM would be noticably faster than your 670).
