Both NVIDIA and AMD partner Club 3D has just unveiled a non-reference version of AMD's Radeon HD 5850 graphics card which it simply calls the Radeon HD 5850 Overclocked Edition with its higher clock rates on tap.
There's more to the card than just higher clock speeds, however. It uses a custom PCB and cooler to make sure its 760MHz GPU and 1050MHz (4200MHz effective) memory clocks are as stable as a rock. But while those increases over the stock 725MHz/1000MHz setup don't seem like much, there's bound to be a lot of headroom for some manual overclocking goodness with this variant.
A bit about the cooler; it is of a dual-slot nature with the use of four protruding heatpipes that run to a large heatsink with aluminum fins of which a centrally positioned fan blows air directly down.
No word on a release date or pricing as yet.
