From what I understand, it's more accurate to say that it reduces CPU use by about 50% (rather than improving performance). If CPU is not your bottleneck, you won't see a performance improvement. If it is (which is common these days), then you'll have twice as many free CPU cycles on your main thread, which will translate into however much improvement your GPU can muster.

Even if CPU isn't the bottleneck, you ought to see some power savings.
Either way, it will make it easier to bolt a monster GPU onto a smaller, more efficient CPU.
(What we do about GPU power consumption is a different problem...)

According to this blog entry, you are mistaken, and it really can improve performanec 54% in a multi-GPU rig.

There seem to be issues with FPS drop, though ('stutter').
