Hi Marek & Filip,
Just a quick one, you will not get a 200%-230% increase over a 470, you will maybe see 15% increase per core since that's the differential between 512 vs 448 cores. You have essentially two individual 480's packaged into one card, you will get 200% increase if you run two jobs separately, and perhaps 140% (guess from speed up seen with GTX295 which is the same format) if you run in parallel across the two chips on the card.
Cheers
Ian

Hi Marek,
We tried two GTX590's yesterday, but there are still no drivers for it under Linux. Thus, I was not able to run and test Amber or any other Cuda based program. Probably missing something?
About the temperatures and noise I was very impressed. The card usually has about 25C lower temperatures compared to GTX470 (40C at normal operations (50% fan speed) and 69C under full load at 95% fan speed. However the noise at 95% fan speed is comparable to those produced by GTX470 at 65-70%.
I expect 200-230% performance increase (ns/day) compared to GTX470, but have to test, and will post the results here.
Don't worry about "big bang" topics, no problem with the card:)
Regards,
Filip
