Can I use the full potential of the 7970 in an Intel DZ68ZV Extreme motherboard (pcie2)?
I am concerned about bandwidth saturation or other bottlenecks.

In particular, it is the Sapphire HD 7970 GHz Edition 6GB card that I am thinking about. I have read the reference 7970 is quite close to the PCIE2 limits and there isn't a real difference on a pcie3 mobo, but what about this Sapphire?!

CPU is a i7 2600. I will be running twin 120hz 23" samsungs, thinking about a third. Used mainly for video processing. Any help much appreciated.

PCI-E 3.0 is backwards compatible with 2.0, no GPU's can even saturate a 2.0 x16 slot (the 7970 6gb included) so you aren't looking at losing much of anything in terms of performance.

At the moment the AM3+ socket mobo's do not support PCI-E 3.0 which the 7970's development bench rig was. Basically, it was designed using 2.0.

TL;DR: You will be fine.
