I currently have a computer set up (saber tooth p67, I7 2600k, 2x EVGA 3GB 660ti, 16GB 1600mhz memory)
would upgrading to a saber tooth z77, I7 3770k bring me any benefit?
While the processor might give you a small performance advantage of maybe 6% (I would say that it isnt worth upgrading). There is almost no value in going to PCI-E 3.0 at this time as even things that say that are using the extra bandwidth are not.
