Other issue been that if your going to game at 1440p some games will increasingly have higher VRAM requirements. I assume your current 680 is a 2gig model?
Means that you may end up having to run things not at max in SLI as youll hit VRam limits.
Im not sure if a better option might be to sell the current 680 and maybe get a GTX 780 or ati 290 with a view of adding a second later.
Just a thought
Been thinking of that as my plan B if I can't get another 680. Now that mantle has come to light I'm waiting to see if I should go to the red side.
No reason to not go with AMD now.
Objectively there's no reason to buy any Nvidia card above the GTX 760 unless you want CUDA/Shadowplay/other Nvidia-only features.
Here's how all the stock cards stack up against each other, with mantle not being taken into account:

You maybe better off selling your GTX 680 and buying a GTX 780 as it best to have 3GB vram for gaming at 1440pHmmmm thing is I'm going to be gaming at 1440P so I want SLI nVidia for the extra resolution. A single GTX 770 isn't going to get my 'minimum of 60fps' gameplay
What about cooler temps, lower noise. Solid dual card support? Physx, G-Sync along with the other bits you mention..
Plenty of reasons to choose a card from either camp. Why do people always have to be one or the other? AMD and Nvidia are both very good..
Not really.There's no difference in temps and noise if you buy aftermarket cards.
