You wouldnt get me buying either 680/790 chipset mobos for overclocking.
Fact, 780I is 680I with one or 2 tweaks, and a separate chip to allow PCI-E2.0 bandwidth. AFAIK, 680Is flaws have NOT been fixed for these boards. 790I has the PCI-E2.0 chip integrated, and will be DDR3 AFAIK. Not heard anything about bug fixes.
FSB holes? Average quad-clocking? (though that is improving) Poor (in comparison to Intel NB) dually clocking? Excessive heat dump? All will still be present, AFAIK.
Tri-SLI: nVidia need to work on drivers to allow better scaling, and they also need to perform the miracle of somehow making the GPU setup not breath-takingly bottlenecked by the CPU.
