[Chiphell]nVidia 9800GX2 PCB Photo

Quite easy for water block makers really, just make a block the same thickness as the current cooler, double sided with entry/exit flow holes obviousley in the top, take the current GTS/GTX block for instance and slap another one on it opposite facing. after all thats all nVidia themselves have done, took 2 cards and slapped another one against it oppsite facing.

its not easy at all, how do you mount the block?
its possible, but its not easy to do...

Then you gotta look at the 3870 x2 the same way, it's just 2 cards slammed onto one pcb, complete with 2 bios's.

Personally, I'm avoiding both camps dual gpu solutions like they were Rosie O'Donnell's bedroom.

hows it the same thing?
1pcb vs 2 pcbs glued together is a big difference.
if done properly the nvidia approach of using 2 pcbs could actually be cheaper, easier to cool and could clock higher if they would use a normal single card pcb as the firt half of the dualcard and would have only one gpu between the two pcbs and not both.
