The Nvidia GeForce GTX 590 is the faster of the two dual-GPU cards but still inferior to the pair of GeForce GTX 570s.
StarCraft 2: Wings of Liberty
We’ve got a familiar picture in StarCraft 2: Wings of Liberty: the AMD cards are competitive in the FSAA-less modes but fail as soon as 8x FSAA is turned on.
