Well you do have a nice card and obviously like having a single gpu solution. You could sell your GTX 670 for $300 or a little bit more and buy a GTX 780. I mean if your going to spend $300 for another 670, you could go the GTX 780 route instead for a little bit more money.
Two 670s will be faster than a GTX 780, like 10-15% faster. But having one fast card is always the way to go to avoid sli hassles.
