A quote from the article:
>> XFX GeForce 9800 GX2 Black edition Review
King of pre-overclocked products has to be XFX, their speed-bin of releasing OCed products is exceedingly fast. I do not think that there is an XFX product out there that is not available as a triple X edition or other series name slapped on top of it. Today will be no different, we received XFXes top of the shelf product, the GeForce 9800 GX2, the cool thing is that this is the new mystified named 'Black edition' series of cards, meaning it comes with a nice pre-overclock and an lovely game bundle.
