Sapphire HD5550 OC

ATI has been sure to cover every possible price and performance range with its HD5000 series cards. We have taken a look at Sapphire’s HD5550 Ultimate with a full gig of ram and today we have the chance to look a little closer at Sapphires HD5550 OC. With an overclock of just over 18% on the GPU, Sapphire is trying to give this sub $100 card the performance of it's faster siblings.
