Just recently picked up 2 of these. Noticed 1 of the cards' cooler is significantly more loose to the card than the other and the cooling shroud is also slightly different as in, the card doesnt stick out as far as the other by a good 1/4" of an inch. The difference in temps is also a bit alarming, almost 10'C idle between the 2.

some other things to note. The card in question seems to lack quality as in the heatpipes do not appear to be as polished as the other and the printed "ASUS DirectCU II" ink-print isnt as nice as the other. Also, there is a noticeable difference in the shade of white light from the power LED's coming from the 2. The "crappy" cards LED's are also dimmer than the nicer one. Lastly, the powdercoat finish on the shroud is much better on the other. the nice cards finish is nice and smooth, while the other is quite rough. Im not sure what the hell is going on here but ive always bought ASUS stuff for their quality and fit/finish...this is some BS...

GPU-Z also reports one of them using Samsung memory vs. the other having Hynix?

The nicer cards Serial starts with F3YVCM where as the crappier card starts with F1YVCM.

crap card...look at the spacing between the shroud vs the heatsink...there is a larger gap on the second, nicer, card:

Im also uploading a video showing the looseness of said card vs the other...you also may be able to see the difference in how much the nicer card sticks out off the motherboard than the other.
