The Radeon HD 3400 and Radeon HD 3600 series cards are pitched as ideal fits for low-cost PCs or quiet PCs, such as media centers where noise is a factor.
Their key features of note are the on-board support for all the codecs necessary to decode Blu-ray
or HD DVD
video at full 1080p resolution
That feature alone makes either of these cards ideal for inclusion in low-cost media center PCs.
