That one website, yep .. ChipHell has a forum post where initial benchmarks of the GeForce GTX 780 Ti have surfaced. There are some photo's included as well, showing a fairly similar PCB and board design towards the GTX 780 and Titan. ChipHell posted five sets of benchmark results including 3DMark tests, Unigine Valley, Aliens vs. Predator 3, Battlefield 3, and Bioshock: Infinite.
The test setup used was a test-bed running Core i7-4960X at 4.50 GHz with 16 GB of quad-channel DDR3-2933 MHz memory. Click the thumbs, photo's and benchmarks are courtesy of Chiphell.
