So you ask yourself how will this card perform in my HTPC. Lets just say you will not be let down. ATI includes in their cards now, two technologies designed to make your media vieweing experience the best it can be. The first is ATI AVIVO Technology, which allows for smooth playback with vibrant colors of your video media so that you have the best viewing that is possible. When coupled with the second part the Unified Video Encoder 2, you have seemless playback and quality for all of your BluRay and HD videos. With these new technologies now integrated into the video card it is off-loaded from the CPU leaving it to take care of the system instead of decoding the video. Below I took a screenshot of an HD video clip of "Traitor" showing the CPU usage during playback. Notice it is only 2% which shows that the GPU is doing all of the work.
