What might be a bit concerning is the length of the card - this design was 13.5-in long and had issues fitting into this full size Antec 1200 chassis.

AMD already got a hold of the guys who posted this so the performance numbers that were along side the photos were taken down before we got to see them. Also, AMD told them that the HD 5970 card seen was an early engineering sample leaving hope that the final retail card will be a bit shorter.
Go see the pictures, etc @ ALIENBABEL Tech

Seems that this will be a very powerful but power-hungry offering...
