Benchmark Reviews posted a review on the XFX Radeon HD5830 DX11 Video Card

The XFX Radeon HD 5830 is one of many new Cypress-based DirectX 11 video cards released by ATI partners in the last few weeks, to great anticipation in the marketplace. Each of the HD5830 cards was designed by the individual AIB partners and there really are no two that are alike, except for minor variations sold side-by-side by a few companies. The high clock rate of the HD-5830 GPU, and its 2 billion plus transistor count, made this design a challenging one for many of the suppliers. The HD-583X-ZNFV graphics card from XFX uses some new power supply technology and a classic cooler design to simplify the Radeon 5xxx design a bit and cut costs, without sacrificing quality or performance. Benchmark Reviews has a retail sample in our lab; let's see how well XFX executed on their strategy.
