There are two schools of thought. One says change the chain often, every 1000 miles or so, to protect the cassette from excessive wear. The second says run the chain until the "stretch" is over 1% (1/8" in 12"), then replace the chain and cassette together.
If you are using Dura Ace or Record Ti cassettes at $200 or more each, than changing a $40 chain very often makes sense. If you are using a 105 or Veloce cassette, then spending $160 on chains to protect a $50 cassette makes no sense.
