Curious to those who have to had replace their X1900XT Cards in their MacPro , had a few questions. 1) Does replacing/removing the card void and warranty? (im getting a new Version2 form Applecare) So id assume no but no real idea if so. 2) Best tools or precautions to use with removing this beast from within? Recommend screw drive to not strip the screws or anything as it seems a slim fit inside the the end of the case and where the two screws holding it in are. 3) Im assuming Version 2 is automatically updated with the firmware? anyone experience issues with the replacement card? Thanks guys!!!
