I'm really looking forward to the 780, I was originally planning to sell my 670 and put the money towards one, except then I read a rumour that it's going to cost almost as much as the Titan, so I'm exploring other options : ( Either way, I'm going to wait until May 27th before I make a definite choice.
Honestly, and I'm not a current AMD user (although I've been AMD in the past), you should just keep the GTX 670 and wait until either the GTX 700 series refresh in June, or the VI release in Q4. The only game that has ever come close to being limited by 2GB of VRAM has been Skyrim with about 16 mods, including texture and particle mods. I've honestly never been over it and I'm running a 1440p panel (main gaming monitor), along with a side 1080p.
Save your money and stick with what you have. Upgrade later on. You won't notice much if any vram limitations at all in gaming on a single 1440p. Wait till June or Q4 to decide what you want. 2GB is absolutely more than enough right now.
