Performance of GTX 590 (or GTX 690)?

How does the GTX 590 (or I guess the 690 when someone tests it) perform in Resolve? Does Resolve see it as two separate GPU's and are people getting the equivalent of two GTX 580's, or is the performance bottle-necked or negligible.

I like the idea of two GPU's on one card, saves on space, but I don't want to move to it if it doesn't offer any performance increase over the standard GTX 580

The 590 is two seperate gpus. Don't know about resolve as I could never get a resolve system to handle the power requirements of the 590 properly, but in my ae tests there is a notable gap in the performance to CUDA core ratio. May be due to memory bandwidth or perhaps to slower clock, or just inefficiency in distributing to two seperate devices. But if you can I would go with two 580 or maybe if Rohit recommends two 680s for resolve.
