Worth selling 680 2GB and buying 680 4GB?

Triple 1200p won't make much difference over triple 1080p. Also, it'll take at least three 7970s for 3GB to even be possibly a barrier. It takes two to three 670s for 2GB to have a few rare issues even with their weaker memory bndwidth and AMD also has better memory handling and some lossless compression going on, so I don't see you running out of memory with the 3GB models in any reasonable situation even several years from now. They'd run out of GPU performance before that point. The 6GB models are extremely difficult to really stress to the point where they best 3GB models without running out of performance.

Hey this guy wanted to sell a 2GB 680 for a 4GB version so I figured at that point a 6GB 7970 GHz is the sane price. But once again, if it were me I would get the 3GB version.

If you need to explain, then I probably went a little too far 🙁 Sorry if I did; I just wanted to make a point on the wasted money in going with one of the higher memory capacity cards. The 4GB 670s and 680s can make sense in a rare few situations, and in those situations, it is true that it's generally better to get a 7970 instead and also that the 6GB 7970s are almost always a waste of money compared to the 3GB models.

Alright thanks for all the answers. It seems as if I'm going to hold off for now and see if any good deals for a pair of 7970's pop up or I'll just wait for the next wave of cards and see what the improvements are.
