+ The rumor has it that NVIDIA GTX 780 Ti will be available in 3 versions: 3GB, 6GB and even 12GB.
+ NVIDIA GTX 780 Ti features 876 MHz base clock and 928 MHz boost clock. I managed to confirm that with stock cooler it can overclock up to 1240 MHz (based on Afterburner readings). I even saw a GPU-Z screenshot with 1851 MHz memory clock (7.4 GHz). I don’t know if these are stable clocks, all I know it was enough to complete multiple 3Dmark benchmark runs, which I saw.
+ Long story short, the GTX 780 Ti is about 6% faster than R9 290X, this is out-of-the-box performance. With overclocking GTX 780 Ti can be 15-23% faster than R9 290X.
