I am in a similar boat (OC'ed 680 with 2GB) and found this guide useful:Anyone running a 2GB 770 with High textures? Normal ones are so blurry at times, but I'm worried what exceeding my VRAM will do to my frame rate.

It says that FPS impact is minimal, but there is an issue with overall fluidity, i.e. framerate drops at some points and tearing.
I am going all in and keeping it at very high, though.
