Tomorrow or rather later today I should finally be receiving my Radeon X800 XT Mac Edition. After a lot of help on this site I decided on that one. My question now is in regards to installation. In terms of work it's a fairly simple installation just remove the stock AGP card and replace it with the new one. Then obviously install the software that come with the CD/DVD. What I wanted to know is if I had to do anything with the original card besides simply removing it. For example do I need to fix or remove something from OSX in conjunction with removing the hardware or will just removing and installing the new one suffice. I save most of my paperwork and CD/DVD's from all my Mac products. However, I didn't find one that had anything to directly do with Video card. I was wondering if I would need something like this. Any help will be greatly appreciated. EDIT: I also wanted to add that I'm using the latest version of OSX.4 just incase this complicated or benefited my issue.
