Apple comes to the rescue with a KnowledgeBase posting that will give you all the details on what systems are capable of using FaceTime. As you may know, FaceTime HD is a new feature of the just released MacBook Pro line, and Apple has taken FaceTime for the rest of us out of beta and made it a US $0.99 app.
While the HD feature of FaceTime is built into the just-released laptops because of an updated higher resolution camera, it doesn't mean those with older equipment are out of the game. Apple says you need Snow Leopard 10.6.6 or above to send a standard definition call. Many, but not all older Macs can view a call in HD, but Apple says it requires a minimum download bandwidth of 1 Mbps.
