還有一篇來自OCW的文章 關於8x00 series在HD的能耐
不過文中只寫到可以降低CPU使用率 不致於總是處於100%
但是確實下降了多少 並沒有清楚的描述：

GeForce 8600 and 8500 series GPUs features a revolutionary new video processing engine. A new video processor (VP) block provides more advanced video post processing to improve overall video quality. A new integrated bitstream processor (BSP) allows the 8500 and 8600 GPUs to perform full HD decode. They are the world’s first video processors to offload from the CPU 100% of Blu-ray and HD DVD H.264 video decoding, enabling playback on mainstream CPUs and providing unsurpassed movie picture quality and low power consumption.
