Well, the work was done by a pair of Finnish overclockers, but the cards used to obtain the 12,483 score were XFX 6800GTs.
This was no easy victory. The two XFX GeForce 6800 GTs with NVIDIA SLI technology were pitted against imposing opposition--including SLI enabled GeForce 6800 Ultras--and, against all odds and mind-boggling improbability, they were able to surpass the competition by leaps and bounds.

Looks cool, is cool, very cool! Not easy to carry around to LAN Parties though.
