I currently have a G4 1Ghz with additional 120gb hard drive and 4 x 512MBDDR SD ram cards. It cant now take 10.5 or 6 and is really slow at watching streamed video on iPlayer etc. Ive been offered a G5 1.8ghz single processor but its hard drive is small and its memory too is a bit lacking. But Im assuming that this will help my iPlayer viewing better than my g4 as it has a slightly faster processor? but is my memory cards and hard drive on my G4 transferable to the G5 so I can add the memory and the HD that I already have? Any help would be appreciated, would love to go to latest mac models but budget never allows.
