I'd take any of them really.
All 3 make rather quiet and cool GPUs that can't really top one over the other.
My preference is the Sapphire or ASUS DCUII
I'd take the Sapphire one as they make the best cooling out there as far as I know. I have a Sapphire card myself and the noise is pretty low, although it cools pretty well.
I made some more research I think I'm going for the Gigabyte because with higher clocks runs cooler and comes second in noise after AsUS. thanks for your help
