The Radeon HD 5770 is the model that places itself at the medium-level range from all the cards on the HD 5000 family: the technical specifications, together with the price make it one of the most interesting solutions when it comes to price/performance. The HD 5850 and HD 5870 models feature, for example, twice as many stream processors, but also a much less convenient price.

The benefits that come with a more efficient cooling system than the standard one makes it possible for Sapphire to have a bigger marging when altering frequencies, but in this review, we’ll be analysing not only how the card behave with its original frequencies (higher than standard), but also the overclocking possibilities.
