Here's my dilemma: I work for a large organization (a university) that is an Apple reseller. They sell end-of-life models for cheap $ when new models come out. I am a somewhat advanced user (Photoshop, Final Cut sometimes, HTML, not really a gamer) but money is tight. Which should I buy (these are both recently discontinued models): For $1330: 20" iMac 2ghz with ATI9600 w/128MB VRAM, 250GB HD, 512MB, Airport Extreme, Bluetooth, 20" display, dual layer Super Drive. No Firewire 800. Money left over to max-out the RAM. OR For $1430: Dual 2ghz Power Mac with ATI9600 w/128MB VRAM, 160GB HD, 512MB, no Airport/Bluetooth, no display, 1 FW 800 port, and possibility for future expansion. Would then have to stretch a bit to buy a 20" display. Easy answer is "Advanced User = Power Mac," but this iMac is pretty powerful. I don't think the second processor gets used very often in the Power Mac anyway. Are there power supply problems like with the previous generation of iMac G5s? Thanks!
