Which Airport card is for the Power Mac G5 2GHz Dual Processor?

Hi & Thanks for the welcome
Sorry to be a complete novice but how to I tell if its a late 2005 dual core? I have inherited the computer and know its about 2 years old - is there somewhere I can look and post its description so you can help me?

Thanks
Darren

This description taken from apple confuses me:

*The AirPort Extreme Card can be installed only in computers that are AirPort Extreme ready. AirPort Extreme Cards cannot be used in AirPort-ready computers with an AirPort Card slot.*

*Requires Mac OS X 10.2.7 or later and AirPort Admin Utility software version 3.1.1 or later to administer an AirPort Extreme Base Station.*
*Wireless printing over USB requires Mac OS X v10.2.7 or later.*

*This AirPort Extreme Card is not compatible with the Mac Pro or the Power Mac G5 Dual and Power Mac G5 Quad computers introduced in October 2005. To add an AirPort Extreme card to one of these systems, please contact an Apple Retail Store or other Authorized Apple Service Provider.*

OK I Trust you 🙂
Could you tell me if this one from ebay is the correct one?

Thansk for your help - very impressed

It says Machine Model: Power Mac 7,2. - therefore which card do I need?

I have this card in my iBook G4 but it didnt seem to fit through the slot which makes me think that its not the correct card for the computer
