Hmmm, I just noticed that with 2 cards, I'll be running both PCI-E slosts @ 8x:
- 2 x PCI Express 3.0 x16 slots (PCIE2/PCIE4: single at x16 (PCIE2) / x8 (PCIE4), or dual at x8 (PCIE2) / x8 (PCIE4))

Is this something to be concerned about too? How much performance will I loose by running 780s in PCI-E 2.0 @ 8x?

As stated *MAYBE* 1-2 FPS.

GTX 690 has a built in PLX Chip that does the SLi between the 2 GK 204's then a 16 Lane communication to the CPU.

You will be fine. I am running Titan SLI on a 2600k and z68 board as well. No worries. Like you said though, be sure to update that PSU thumb.gif

Your overclock is good. It will be fine without upgrading you cpu thumb.gif
