Although Blu-Ray and HD-DVD are on the way, DVD videos remain the primary method of watching movies. Companies like NVIDIA and ATI have made video quality a key feature in their next generation products. It used to be that things like MPEG-2 acceleration would be described in just a bullet point, but now we have ATI AVIVO, NVIDIA PureVideo, and XGI TrueVideo. In this article, I will be using the HQV Benchmark DVD to evaluate mainstream GPUs: the ATI Radeon X800 XL ($270), the GeForce 6600GT ($170), and the XGI Volari 8300 (esp $50). As you can see from the difference in pricing, by mainstream, we're just talking about a GPU that's not a GeForce 7800 or Radeon X1800.
