Nvidia's GeForce GTX 590 to launch this month

Nvidia's upcoming GeForce GTX 590 dual-GPU graphics card is expected to hit the streets before the end of the month, although sources indicate that the launch has hit a last-minute speed bump.

While little is known about the as-yet unannounced board, a leaked briefing slide indicates that the card will include a single central fan, 3GB of GDDR5 memory, and a pair of Nvidia Fermi GF110 GPUs - thought to be specially-selected GeForce GTX 570 parts.

The card is Nvidia's answer to rival AMD's recently launched Radeon HD 6990, which likewise packs two Radeon HD 6970 chips behind a single central fan - although boasts 4GB, rather than 3GB, of graphics memory.

Nvidia is playing its cards very close to its chest with this launch, but a report on Chinese-language site XFastest suggests that the GeForce GTX 590 will be officially launched on the 24th of March - two days later than earlier rumours suggested.

While no reason for the rumoured delay was given by the unnamed sources, the short delay shouldn't affect Nvidia's plans too much - although at this point the company will be keen to see the board launch so as to offer a competing solution to AMD's Radeon HD 6990, which is currently the card of choice for gamers who don't give a hoot about price.
