The reason the GTX 590 doesn't improve is a temperature issue, the card clocks down, when to hot and goes back to the original clock when cooled down enough.
That's the reason the z version doesn't improve the runtime.

Thanks Fred

What is the difference between the 41g and 41z apps?

Do you have data for the 580 running stock/reference clocks?

Do you have data for the 580 with the 41z app?

Thanks...shopping for the next gpu now

I expect the 580 to run similar to the 480.
The Z is the new Lunatics Alpha version, as you can see it's mostly optimized for the latest cards, starting with the 4xx series. The gains are spectacular.
