And a small bit of the news : "The card is cooled by a customised solution from Arctic Cooling with nickel plated heatpipes and fins, featuring three low-noise dual ball bearing fans and developed specially to mate with the SAPPHIRE original design pcb. This efficient solution also provides scope for further performance tuning."

That card would be sweet for some massive eyefinity setups. On a regular resolution on a single monitor you'll get a decrease in performance I bet, compared to the 2GB version.
So is this the overclocked version (OCed to 5870 speeds) dubbed the infamous 5990?
It's probably the fastest card, because the only other custom HD 5970 that I know of that has been tested right now is the ASUS RoG Ares HD 5970 4GB version which has its clocks at stock 850MHz/1200MHz, while this card has it at 900MHz/1200MHz.
