NordicHardware has it on good authority that Nvidia plans to launch its dual-GPU GeForce GTX 590 graphics card this month. A release date isn't mentioned, but Nvidia is probably trying unveil its flagship in the same timeframe as AMD's competing Radeon HD 6990 (codenamed Antilles).

The GeForce GTX 590 will pack two GF110 graphics processors offering a total of 1024 CUDA cores, 3027MB of GDDR5 memory, dual 384-bit memory buses, 128 texture units, and 96 ROPs. That effectively doubles the specifications of Nvidia's single-GF110 GeForce GTX 580.

NordicHardware notes that Nvidia has chosen to enable the maximum number of CUDA cores while reducing the stock clock frequencies and voltages for improved power consumption. The GeForce GTX 590's TDP hasn't been revealed yet, but the GTX 580 is rated at 244W.

The site couldn't score shots of Nvidia's reference card, but it supposedly carries a full-cover cooler with a 9cm fan in the center – not unlike GeForce GTX 295. The GTX 590's pricing also remains a mystery, but you can expect it to cost upwards of $700 considering the GTX 580's $500 price tag.
