Hi guys I'm about to get given a PowerMac G5 single-core 1.9Ghz. I'm looking for an upgrade solution as I'm not sure if it will have enough power for what I'd need to use it for (music production). I've done a bit of searching on here and can't find a complete answer, but the gist of it seems that as well as the processor (I'm planning for a 2.5 Quad) I would need a PSU and a logic board to go with it. Is this all I would need to upgrade? Or are there more things I have to look at?
