This is not nearly as exciting as the Titan X's, but ohhhhhhhh boy it has me excited.
For the last 3 years or so I thought my X58 4Way SLI and Gigabyte X58-OC were dead. I tested the GB OC board tonight with my ES X5570 CPU, it stopped POST at C1 and wouldn't output video/boot correctly regardless of any combination of things(which is what it did in the past as well). I was about to pack it up again as dead when I decided to throw my old i7 960 (retail) in it just for the hell of it. It booted! So the X58-OC works(!), and potentially my old E762 4XSLI will as well, I'm going to test that one tomorrow.
Only issue is for some reason I'm not getting power to USB keyboards, so I'm not totally out of the woods yet(might need a PS2 one?), but getting to that screen is more than I've gotten before. I had the list of POST codes pulled up on my Surface there, and yes, Dr. Pepper is required for 1:00AM testing.
Edit: C1 is memory initialization error, so I thought maybe the IMC was dead and that the 960 might work, that hunch paid off.
