AMD this morning added its first DirectX 11- and OpenGL 3.2-capable desktop graphics card below the $100 mark. The ATI Radeon HD 5670 sits just above the 4670 and primarily improves on its predecessor's performance by including more stream (visual) processors at 400 versus 320. Besides the enhanced graphics, it's also the least expensive card to support Eyefinity and can drive three displays at once, including merging them into one large virtual screen.
