Dual Core Gigabyte GV-3D1 vs Dual 6600GT SLI Performance
"Are two better than one? Yes, in most cases. From our benchmark results, the GV-3D1 actually runs slightly faster than dual 6600GTs at the same clock speed. Since this card will be bundled with the motherboard as limited edition and no other manufacturers produce similar card at the moment, it will be a great collector's item for PC enthusiasts. The GV-3D1 is definitely a better choice if it is priced lower than two 6600GTs, we will update this page once the pricing information is available. "
