Benchmark Reviews posted a review on the ATI Radeon HD 5970 Hemlock Video Card

ATI now dominates the graphics industry with their DirectX 11 Radeon HD 5000-series video cards, which allows them to enjoy current-generation gaming on Windows 7 and Vista. The ATI Radeon HD 5870 has already beat the worn and weathered GeForce GTX 285, just as the Radeon HD 5850 and HD5770 do at their respective price points. By combining two Cypress XT GPUs together on one PCB, the ATI Radeon HD 5970 video card will now compete against the very best NVIDIA can offer: the GeForce GTX 295. In this article, Benchmark Reviews tests the 'unlocked' Hemlock GPU against the top graphics products available and demonstrates just how much ground AMD has gained in a few short months.
