Folks who are looking to build a new HTPC will want to take note that HIS is gearing up to launch another low-profile graphics card in the form of the Radeon HD 5550. The fact that this card is passively-cooled should help to keep noise levels low for your audio enjoyment. This card integrates a 40nm Redwood GPU, 400 Stream processors, 128-bit memory interface, 500MHz core clock, 1GB DDR2 VRAM and a heatsink to disperse the heat off the graphics card. The card supports DirectX 11, full 1080p video playback, D-Sub, DVI and HDMI video outputs. The Radeon HD 5550 will be available in stores over the next few weeks, though pricing hasn’t been announced yet.
