Hi, I've got some questions about upgrading gpus in Power Macs: 1. I have recently installed Nvidia Quadro FX4500 in my PM G5. Is there any good reason to install the stock gpu in 8x PCie lane, except for using more than two screens? I mean, is there any performance improvement by using two gpus instead on one? 2. Is there any way to flash ppc gpu for using it in a PC? Ive tried to google it, but no results. 3. What do you think guys, about creating a spreadsheet document, where each one of us could write informations about gpus upgrade possibilities for each model of PM, including info about vram type and size, need for flashing etc.? So everyone could just simply open the document and find all the informations one can need while trying to upgrade his PM?
