BenchmarkReviews checks out this dual-GPU beast and concludes it offers unmatched top-end DX11 graphics performance. The main cons are the high price of course, and the noisy fan.

"If you're an enthusiast gamer who demands only the highest level of performance that far surpasses mainstream standards, then it's your lucky day because the AMD Radeon HD 6990, code named Antilles, was designed to do exactly that. Using a new VLIW4 shader core architecture and equipped with 4GB GDDR5 256-bit video frame buffer, dual Cayman GPUs offer a total of 3072 stream processors. While the Radeon HD 6990 accomplishes the performance of two Radeon HD 6970's in CrossFireX, AMD also adds accelerated multimedia playback and transcoding, AMD HD3D stereoscopic technology, and support for the 3D Blu-ray multi-view CODEC (MVC). The AMD Radeon HD 6990 utilizes several new MSAA modes including Enhanced Quality Anti-Aliasing (EQAA), which Benchmark Reviews tests in some of the most popular DirectX-11 video games."
