PowerColor is the third manufacturer that we know of that has officially announced a dual Radeoon HD 2600 XT card and PowerColor simply calls theirs the PowerColor HD 2600 X2. Each of the GPU's are clocked at 800MHz, which is nothing out of the ordinary. The card also has 256MB of GDDR3 memory per GPU and this is clocked at 700MHz, the same as for PowerColor's normal Radeon HD 2600 XT GDDR3 card.
The picture of the cooler looks almost as if it's computer generated in the picture, but at least PowerColor seems to have designed a fairly small card, just like GeCube and unlike Sapphire. However there's no information whether or not this card needs additional power or not. A single fan should keep the noise down as well and it appears to have a rather chunky heatsink. It's also got four DVI ports and we expect two of them to be able to carry an HDCP encoded HDMI signal via an adaptor.
We don't have a price, or any availability date for this card, but you can check out the product page here
