Hello all, I purchased my first G5 tower about a month ago, and just ordered an X800 XT video card to replace the one that came with my system. This is the first Apple non-laptop machine I've owned. I remember from the last time I upgraded the video card in my PC that I had to jump through hoops, including reinstalling the OS for optimal gains. What is involved in replacing the video card in a PowerMac? Anything other than powering down, taking out the old card, putting in the new card, and powering up? Do I need to do anything driver-related? I imagine any instructions I get with the card may tell me some of this, but I would like to be prepared Thanks in advance!
