Gigabyte Radeon HD 6450 Graphics Card

Multiple display support for your HTPC (Home Theatre PC), video acceleration and 3D video playback without breaking the bank. That’s the Gigabyte Radeon HD 6450 graphics card with AMD Eyefinity technology at only R540.

This card is ideal for someone looking for something better than integrated graphics. “It is small, uses very little power, delivers good image quality, and can accelerate Blu-ray 3D over HDMI 1.4a.” 

Further quoting the Tom’s Hardware review, “As an HTPC card, though, that’s where the new Radeon HD 6450 stands out.”
