Any high end card with the fan set to 100% will sound exactly same. Under normal use, with good case ventilation, and no GPU overclocking, the fan will seldom if ever hit 100%. (he is applying the fan speed manually here with an overclocking tool) Put the side of the case on, and it will muffle it a little, but in a nutshell, a high end card is going to make a little noise if you push it hard, that is all there is to it.
