Currently I have a GTX 680 and I was thinking about buying another one and putting then in SLI. My question is, if my current 680 is a palit 4gb, would sli work if i bought a palit 2gb?

Yes, but you'd only be able to use the 4GB as though it were a 2GB card, and because vram in SLI doesn't stack, you'd only have 2GB usable VRAM... meaning you'd lose half your VRAM. This would only matter on a triple monitor setup or if you're using a resolution greater than 1080p, but still.

Thankyou for the fast response. I think I'll just save up for the 4Gb card.
