So I have a PowerMac G5, love it, use t all the time! If only it could run Netflix, anyway. I would love to see if I could get this running faster, I've got 2GB of RAM, 2GHz Processor, and I believe a 5400 RPM Drive. I am assuming to get applications to load with more ease that would be a 7200 RPM and 4GB of RAM? OR is it just the PowerPC Processor?
