Today we take a first look at the new single slot HD7850 graphics card from AFOX. The company claim this is the ‘world's most powerful single slot graphics card' and our review will highlight Crossfire performance. If you are building a space restricted media center but don't want to compromise when gaming, are these the products you should be shortlisting?
AFOX as a brand name may be unknown to our readers, however they are a spin off from parent company Foxconn (Hon Hai Precision Industry Co) a Taiwanese multinational electronics manufacturing company based in Taipei. Foxconn manufacture a huge range of products, such as the iPad, iPhone, Kindle, Playstation 3 and Xbox 360.
There really is no question that their manufacturing capabilities are world class, so we have high hopes that the AFOX HD7850 Single Slot may be one of the best choices for a tiny media system. We already know that a single HD7850 can run out of horsepower at high resolution with some of the more demanding engines, but how about two?
