Zotac and BFG have followed other partners with their announcements of Nvidia's Geforce 9800GX2. As all other partners' cards, these two also have reference cooling and reference clocks.
Just for those that somehow manged to miss the reference clocks of Nvidia's Geforce 9800GX2, these two cards are working at 600MHz for the core, 1000MHz for 1GB of GDDR3 memory and 1500MHz for Shaders.
The only difference is that Zotac has decided to do a world exclusive game bundle with Lost: Via Domus. It is always nice to see a game bundle, because it is good to know that you get some extra value when you buy a card from a certain partner.
