AMD's new Radeon HD 4550 comes in a passively cooled version without fan. Such a noiseless experience is crucial in media PC designs where you don't want to be distracted by any fan noise. Also included is a native HDMI and DisplayPort output for connection to your big screen. With a price of around $50 the card even offers some potential for casual gaming.
