Sapphire Radeon HD 4650 & 4550 Overclocked Editions Review
 

The 4850 and 4870 hit the market with a huge bang this past summer forcing Nvidia to drastically cut prices and at last giving ATI a better card in technology and in performance. In aiming for the upper-mid range rather than trying to build the fastest card possible they also have a great architecture to scale down from. We've looked at a few of these cards and today we have two more from Sapphire, their Radeon HD 4650 Overclock and their low-profile Radeon HD 4550.
