The tour continues
A closer look shows the twin DisplayPort interfaces, ferrying both audio and video to DisplayPort-capable displays.
The choice of outputs is up to the card partner, and there's no reason why one can't have HDMI in lieu of DisplayPort, or two DVI connections.
Two digital displays can be run concurrently, irrespective of the format (DisplayPort, HDMI, DVI), and monitors can be set to independent resolutions and overlays.
All connections carry HDCP-protected support for playing back Blu-ray or HD DVD content, for example.
Here's a quartet of mid-priced cards that vie for the cash in your pocket. At the top, and derived from a full-fat architecture, is the GeForce 9600 GT (£70) followed by a Radeon HD 3850 (£70), Radeon HD 4670 (£50?), and Radeon HD 3650 (£35).
These are among the volume-selling SKUs that you'll find a whole host of mid-range systems.
There isn't too much to differentiate the two smaller Radeon HD cards, but the underlying GPUs are vastly different, as our benchmarks will show.
