While the launch of AMD's flagship Radeon HD 5800 series architecture and graphics boards look to have set the tone for the remainder of the year most likely, it's already very much apparent that their ATI graphics division haven't been allowed to rest on their laurels despite being the first to market with DirectX 11 capable parts. Instead, the company are pushing hard to bring DirectX 11 functionality to lower price points, and today sees them do just that, with the launch of two new boards and another new GPU (codenamed "Juniper") with an eye towards the mainstream and lower-end of the performance graphics market. These boards come under the Radeon HD 5700 series banner, and thanks to AIB partner Sapphire we've been able to take a look at both the Radeon HD 5770 and Radeon HD 5750 to see what they have to offer.
