Last month AMD unleashed what went on to become the worlds fastest single-GPU graphics card by a convincing margin, the Radeon HD 5870. This was followed shortly by a slightly watered-down version known as the Radeon HD 5850. The latter has proved to be very competitive, playing second only to its bigger brother and at just $260, it stands without a doubt as the best value high performance offering available at the moment. Continuing with the successful rollout of its Radeon HD 5000 series, AMD is now moving to attack the sub-$200 market, and hopes to keep the momentum going with the Radeon HD 5770 and 5750. Codenamed Juniper XT and Juniper LE, respectively, the first is said to cost just $160, while the lower-end 5750 will cost between $110 and $130 depending on memory configuration.
