There's an early sighting on the web of an upcoming custom-designed graphics card from ASUS based on the HD 5870 which is speculated to come out as the EAH5870-TOP.
Of course, this card will come factory overclocked and uses a superior high-performance cooler as shown above. However, actual clock speeds have not yet been revealed, nor pricing or availability (though it's likely we'll hear more details come CeBIT 2010 next month).
ASUS also looks to be readying up a non-reference HD 5850 based card dubbed the EAH5850 DirectCu. This card looks to be focused more towards providing a quieter and more efficient solution as opposed to pushing the speed barrier. The image below makes mention of the cooler being 20% cooler and 35% quieter than the stock cooler used on the 5850.
Again, no word on pricing or availability for this card as yet.
