According to unnamed sources, Nvidia partners are practically ready to roll, and the company could launch its dual-GPU product before the end of 2010. Unfortunately, that's unlikely to happen. Word has it that Nvidia is waiting for AMD to ship its dual-chip solution, the Radeon HD 6990 (codenamed Antilles), which is on track for the first quarter of next year.
Nvidia currently holds the crown for single-GPU performance with its GeForce GTX 580, and it seems the company wants to ensure a dominate position in the dual-GPU market as well. By delaying the GTX 590 until after the Radeon HD 6990 arrives, it's suggested that Nvidia will have an opportunity tweak its contender before shoving it into the ring.
