Anandtech.com: All things considered, the Radeon HD 5000 series has gone very well for AMD. When they launched it just over a year ago, they beat NVIDIA to the punch by nearly 6 months and enjoyed a solid term as the kings of the GPU world, with halo parts like the 5870 and 5970 giving them renewed exposure at the high-end of the market while mainstream products like the 5670 redefining the HTPC. Ultimately all good things come to an end though, and as NVIDIA has launched the GeForce 400 series AMD has needed to give up the single-GPU halo and lower prices in order to remain competitive.
