World Record: Galaxy GTX 780 HOF Overclocked to 1.85 GHz
A team of overclockers from HKEPC -- Mad222, Stephen Yeong, John Lam, and Mr. Wong -- have set a world record for overclocking the GTX 780 graphics card. Using liquid nitrogen, they have managed to get the card to outperform even the dual-GPU Radeon HD 7990, using the single-chip GTX 780.
The clock speed they have achieved is 1855.2 MHz GPU; they got the memory running at an effective speed of 7.4 GHz. At these speeds the card scored a grand total of 41,180 points in the 3DMark Cloud Gate benchmark, which is a very, very respectable number, and according to other sources, even a world record for single GPU performance. For comparison, the GTX Titan scores about 27,000 points stock, and the Radeon HD 7990 scores around 32,000 points, all with a degree of variation depending on the configuration used.
The CPU used for the benchmark was an Intel Core i7-3960X, which was clocked at 5.5 GHz.

for hardware of that calibre?

Nice try, but you can't compare 3dmark Vantage results with 3dmark Cloud Gate results.
true but the highest 7970 up there is only clocked at 1350 gpu his is way over that as well as his memory clock so i wonder what hed score
also that site is saying those i7s are 32nm haha they are 22nm
I'd be more interested records set under the condition of running 24 hours unattended under full load.
LOL....:D
