Modders-Inc posted a review on the Sapphire Radeon HD4650 OC Edition 512mb GDDR3

Are you looking for a budget graphic card for your HTPC with enough kick to really game with? A graphic card that is energy efficient but also has enough power to play the latest and greatest games. If that's not enough for you how about you throw in 320 stream processing units, up to 1GB of memory and support for Microsoft DirectXR10.1 games, the ability to watch Blu-Ray movies and play HD content. Well Sapphire Tech has done just that with the HD 4650 OC edition graphics card. Not possible you say?
