DUAL 6GB AMD FirePro D700.

This is a cheaper option than buying the cards only and you are getting a professional to do the upgrade for you.

You will need to send in your existing mac pro for it to be upgraded. The old cards will be kept and swapped out for DUAL 6GB D700.

This service is for upgrading working cards not faulty ones. For replacing faulty you can buy the cards only without the upgrade service.
