Evga GTX 580 Hydro Copper 2 , has a full card water block and is the best card out there , the version I have has 3 gb of ram and is factory clocked at 850 mhz. I play Call of Duty Black Opps and the temps never get out of the 40's c. I have 3-way SLI running into a quad radiator. The cpu and ram are on a seperate loop. I checked out the link you supplied and the question I have is if the PNY card is a water cooled card why is there a fan on it and it takes up two slots? If you check out the link below you will see a proper water cooled card and a single slot solution as well.
