Radeon HD 5850 review (CrossfireX) @ Guru3D
Quote: "Today we'll test and review the Radeon HD 5850, we'll check both the single GPU performance but also will check it out in CrossfireX multi-GPU mode. This card promises to go neck-on-neck with the 349 USD GeForce GTX 285 in terms of performance. The Radeon HD 5850 however comes with full DirectX 11 compatibility, Eyefinity and some sheer brutal rendering performance in both gaming and compute features."
