Hi, I'm back, went on vacation and hadn't had time to flash the GPU yet, but will hopefully attempt this weekend. Anyway, the point of this thread is to ask about multiple GPU's in the powermac. I read that you can put 4 6600's in the G5 (from the Apple site) to run 8 monitors (pretty cool). but that lead me think what about putting two x1900s in it? (one drawing power from the MB and the other getting power from the IDE via a splitter). Has anyone done this?
