HIS X850XT Platinum IceQ II
 

Between the HIS card and ATI's card, the performance and features are
identical, so the main advantage of the HIS X850XT-PE is the improved
cooler. While we knocked it earlier, it does run quietly and cools on
average about 12°C cooler than ATI's cooler. Other than that, deciding
between the cards is going to boil down to pricing and availability.
