Beautiful card. Works nicely with watercooling. Only flaw is the sag. This causes the cooling to separate from the card and push temperatures +- 30C higher. Using a simple "irrigation riser" from Bunnings for $5, cut to size solves this. Bizarre that a $1600 card can have this design flaw.
Great (looking) card, running it on air myself and it keeps pretty quiet under load. Just beware that it weighs quite alot, so keep this in mind when building. I myself have it installed vertically in a HAF XB EVO case by Coolermaster.
