Sources from Gigabyte claim that the new card will be the best performing single-board graphics systems - at least when current scoreboards are considered. Benchmark results point to about 20,400 points in 3DMark 03 and about 9500 points in 3DMark 05.

But here is the sweetest part of all
sources said that the GV-3D1-68G will cost about 10 to 15 percent less than two 6800 GT cards in a package.
SLI just got burnnnned.
Also, compare to the 7800 score set by the G70 in 3DMark05 (Source), and dual GPUs look damn good from a benchmark point of view. Mind you I'd have to see how these perform in real games, and they'd have to make the card smaller or more practical for a chassis, but this is undeniable proof that SLI and dual card solutions suck next to the real thing.
