Hi everyone So I've just gone and got myself a G5 quad core 2.5GHz, mostly for nostalgic reasons but that's by the by. Anyway, after doing some digging around the internet, it seems that the very best GPU that this machine can support officially is the NVidia Quadro FX 4500. However, after more research I have seen that people have had success in flashing a GeForce 7800 GTX 512MB with a custom ROM, usually a modified Quadro or 7800GT ROM, and have it working on a Power Mac G5. My question is, does anyone know where I can obtain this ROM? The threads turning up in my searches are very old, and even though there are links to supposedly working ROMs on them, the response seems to have been mixed at best. On top of that, the one particular guy seemed to be the authority on this particular subject, Japamac, has not been seen in years. Any help or possible leads you can provide will be greatly appreciated. Cheers!
