I bought the ASUS card the first day it was available on NewEgg, but got one of the many bad ones. See NewEgg customer feedback -- way too many crash repeatedly at stock speeds. Mine crashed repeatedly even when underclocked. I reluctantly RMA'd it. It was very solid and very quiet (silent up to 58% fan speed), would have been great if it worked. Got my second choice, Gigabyte, very good, zero problems. Not as quiet under load, but quiet enough. I was hoping this article would mention the ASUS problem and speculate as to the cause and solution. Also, would be nice to read about the various fan control-overclock utilities of the cards, especially since any of them (I think) can be used with any 670 card. Which is best? PrecisionX from EVGA may be. ASUS' utility probably contributes to its problems.
Final comment: this article should have been released in the English TomsHardware last month, shortly after it appeared in the German. I watched and waited, hoping for guidance before choosing my replacement card. (The Google translaction of the German site is not very good.)
