I'm using 4x old GTX titans ( Kepler ) without problems. So the 780ti should also work. I went back to Bios 5701 as the newest bios has a problem with the first slot running at Gen 3.
Strange how temperamental this mobo is, seems like its a lottery getting a good one which isn't very encouraging for Jirkas, I got lucky I guess, but from what I know the SR-2 you are using is also riddled with problems, and EVGA development and support gave up on it a few years back, as it was too much of a headache.
I rarely use CPU's for rendering anymore, so my next build will probably be a single socket. the X99-e WS maybe, with 4 x Titan X ( Pascal) or maybe I will wait until this time next year and build on the new platform. Hopefully there will be a fully loaded Pascal by then...
The Z10 and X99 are expensive plus the CPU's, but they may offer a more future proof platform, especially compatibility wise.
Have you cross checked on somewhere like CPU Monkey to see which V3 or V4 Xeons may offer the same processing power as the old 2670? I haven't checked but the lower end V3/V4 Xeons may match the power of the old 2670's but cheaper.
