Because no other card has 2 gpus on the same pcb.

*drools* very nice, if only I had the money...
Looks like these will work in crossfire easily; infact just imagine 2 of those cards overclocked = insane. :P

Looks like it is going to have the same problem the stock cooler has. One GPU is going to run a lot hotter than the other because it is being cooled by the hot water from the first GPU in the loop. Though that is a common problem with certain watercooling loops with multiple cards anyway, and with water cooling the temperatures should still be more than acceptable.

lol... nah it's good the way it is... thats a pretty solid chunk of copper, something like that would heat and cool pretty evenly with any decent flow rate; it devinitely wont have the problem of cooling one GPU more than another and if it did it would be too insignificant to matter.

Not exactly true. ATI did this before, two GPU's on one PCB. Anyone remember Sapphire Radeon X1950 Pro Dual? Heck, it was in stock @ Newegg until recently.


There is a review right here on TPU.

Anyways...

I think two separate blocks would be a better idea for these cards, in fact if you are liquid cooling your entire system (CPU, NB, SB, etc) and have a multi GPU setup (either SLI/Crossfire, or a multi GPU card) it's not a bad idea to run two separate loops (two liquid cooling systems side by side). One dedicated to the GPUs, other to the rest of the system. Either way, way more room to experiment on X2's than with GX2. For sure.

Anyways, blocks are getting cheaper by the day.
The one below can be found for $20.80 @ Aerocooler.com

Agreed, I think that would be a much better design, but would require a more complicated tubing setup. Advantages/disadvantages...blah blah blah.

You should find a local machine shop and have 50 of them made. Then sell them on the internets

Ok, let me rephrase, the only ATI designed gfx card with dual gpus on the same pcb. lol. Iirc, wasn't that dual gpu 1950 a Sapphire in-house design?

since sapphire make the generic ATI cards, one could theorise it was something of a prototype, and had some form of approval from ATI.

They were only ever sold under the sapphire name, that much is for sure.
