Apple Thoughts: ATI Graphics Card Issue for Mac Pro Finally Addressed by Apple

"Apple recently posted a support document acknowledging an issue with ATI X1900 XT graphics cards that shipped with Mac Pro systems between August 2006 and January 2008."

If you have one of the affected machines, make sure you get it in sooner than later, as the program lasts from three years from date of purchase or until January 31, 2011, whichever provides longer coverage. If you have already swapped out your card, you can dig up the old one (if you still have it) and bring it in to any Authorized Service Provider or Apple retail store and get some cash back.
