    Here is the first picture of XFX' flagship graphics card based on the AMD Radeon HD 7770 GPU, the XFX Radeon HD 7770 Double Dissipation Black Edition. The picture reveals that XFX is sticking to a slightly-modified version of the AMD reference PCB, its variations don't appear to go beyond a red-colored DVI connector. It's the cooler, where all the action is. XFX used a slightly downscaled version of the "Double Dissipation" cooler it designed its Radeon HD 7900 series graphics cards with.

    The cooler appears to use large copper plate that makes contact with each of the aluminum fins that run the entire length of the card. These aluminum fins are then ventilated by two fans that spin at low speeds (low noise), ensuring even ventilation, and better cooling compared to AMD reference cooling solution. A picture of a portion of the product box has text that claims this cooler is up to 13 dBA quieter than the reference design cooler, and up to 7 °C cooler. The "Black Edition" moniker would indicate that this card is factory-overclocked.

    Why the hell should this card require so much cooling? :banghead:

    Right where I want to be
    b/c that's not a lot of cooling, it's a small card which makes the shroud look bigger than it actually is or does it need to be passive for you to be satisfied.

    It doesn't, it's just marketing (now with Double Dissipation!). All they did was whack on 2x80mm fans on the same old heasink design used on about half the 5770's.
    Edit. the heatsink might be, ever so slightly, larger than what was used on my old HIS 5770 that had a 92mm fan.

    This can still haz 2GB. Anyway, the performance level doesn't really justifies having 2GB of VRAM, CrossfireX though is another story but for 319$? screw that, just get a couple of HD6870
