GeForce GTX 590 features Surface
It looks like a board-partner presentation slide showing some information (though limited) on the upcoming flagship product from NVIDIA.
The slide does confirm some of the rumors like full shader processor count, dual-slot design and 3 GB of graphics memory. The slide also notes a 12 layer PCB (which is a lot really) combined with a 10-phase power design. Typically that would be 8+2 for memory.
Anyway, the slide does not reveal much other then the semi-confirmed rumors out there, but I assume everybody likes pretty pictures.
