Well first of all that Dual core card is made by Gigabyte only.
If you wanted to know.
Do you know how much that card costs its about $550 and doesnÂ’t have a SLI connector on it if you look, like any other SLI card.
Gigabyte have chosen not to make any dual core cards using 6800GT or Ultra chips because they said it would cost way to much to make and sell and hardly anybody would be able to afford it.
So there wont be 2x dual core 6800GT's or 2x dual core 6600GT's because the dual core 6600GT's doesnÂ’t have a SLI connector on it.
