Unless you want to OC, or use Intel RST (onboard RAID) or SRT (poor man's hard drive cache)
then there is little difference.
While a rock stable OC always
makes sense to me on large video editing it is not that big a gain. The CPU is the predominant power behind Photoshop and video editing, with generally no real contribution by the GPU. That, however, is evolving.
I will say I think presently a GTX770 is overkill for video editing and I am not even sure if Pinnacle uses (or uses much) parallel processing capabilities of the GPU. I note Adobe has expanded their parallel processing routines for GPUs and undoubtedly this trend will (forgive the pun) accelerate. But you can always buy a great card when such routines are present and firmly established as beneficial.
Looks like a quality board to me. Not sure why you are asking after
the purchase though.
