While the card doesn't feature any additional memory, it does come with a custom all-copper water block with 3/8" fittings.
The new card will come clocked from the factory even higher than the AMP! Edition, with clock speeds of 722 MHz, 2700MHz, and 1584MHz for the core, memory, and shaders respectively.
Unfortunately there is no mention of availablity or price in the press release, which can be found here.
Cooled by a custom all-copper water-block, the ZOTAC GeForce GTX 285 Infinity Edition is able to operate at higher clock frequencies while maintaining lower operating temperatures than the existing award-winning ZOTAC GeForce GTX 200 series graphics cards. The ZOTAC GeForce GTX 285 Infinity Edition ships with a water-block preinstalled with standard fittings that enable users to integrate the card with existing or new water-cooling systems.
"We saw that high-end enthusiasts were using water-cooling systems increase overclocking performance and lower operating temperatures. With our ZOTAC GeForce GTX 285 Infinity Edition, we're able to offer a water-cooling ready high-performance graphics card that integrates well with existing water-cooling components at a relatively low cost," said Carsten Berger, marketing director, ZOTAC International.
