XFX announced its Radeon HD 7870 Double Dissipation graphics card. The card features the same large-version of the company's Double Dissipation cooling assembly that's also featured on some of its Radeon HD 7900 series products, making it a monster overclocker. The Double Dissipation cooler uses an aluminum fin stack to which heat is conveyed by copper heat-pipes, which draw heat directly from the GPU die. The fin-stack is then ventilated by two "GHOST" fans, which are whisper-quiet. The R7870 DD from XFX also features a 5-10% factory-overclock. Slated for market-availability on, March 19 like the rest of the Radeon HD 7800 series products launched today, the XFX HD 7870 Double Dissipation will charge a small premium over the reference design.
