  1. 1) There is no such thing as an HD4970 (I assume you meant the HD4870)
    2) According to ATI's Crossfire Compatibility Chart, you can only crossfire an HD4870 with another HD4870 or an HD4870x2. You can only crossfire an HD4670 with another HD4670.

  2. sory i ment 4890
  3. If you have a second monitor, you can use the HD 4670 to drive that monitor.

    Otherwise:

    1. Keep it as backup.
    2. Sell it.
