The Sapphire Ultimate Radeon HD4670 is a passively cooled graphics card with plenty of features other than its silent operation that should appeal to HTPC owners. With an integrated HDMI port, DirectX 10.1, and Shader Model 4.1 support, it offers some of the things you look for in a gaming graphics card, but with an obvious focus on home theater performance. http://www.bigbruin.com/2009/sapphire4670_1
