So there has to be something special about this graphic card : it comes with a Waterblock, Radiator, Pump and Tubing so you should be able to watercool this graphic card without any problems. This results in a very quiet 3D card, and possibly very good OC results but is this worth the insane price? Also notice that it has a 5.1 CH Sound Card and a FireWire Card included, and that it operates at higher speeds than the standard GeForce 5900 ULTRA's.
Bonus items included:
This all might sound very nice, and it is also good that watercooling is becoming more popular among manufactors. But still this card retails at an extreme price, and I really can't imagine that they will sell a lot of them. For that price you can buy a whole new computer!
But it might not be an entire loss of R&D costs for Gainward because they already gained some more experience with watercooling now. But I hope WC will not become a necessity in future, chip makers like NVIDIA, ATI, Intel and AMD should concentrate on making less hot chips, instead of increasing the need for more powerful cooling solutions.
