What They Can Really Do
My G5 is my work horse. The apps I use on my computer are listed below as well as version numbers. I recommend that you download and save all disk images for applications simply due to scarcity.
Mac OS X Leopard 10.5.8
Microsoft Office 2008
iWork 09
iLife 09 (Slower Macs May Have Limited Features)
Adobe CS4 Suite
Xcode 3.1.4
Spotify
Skype 2.8
Audacity
GIMP
Google Earth
Open Office
Dropbox
Mactracker
AppleWorks
Final Cut Pro 6
Now my G5 isn't exactly top of the line, yet it handles what I throw at it and my MacBook Pro is used mainly on the go and for school.
Specs:
PowerMac G5 Dual 1.8 GHz, 2*1TB Western Digital Caviar Blue, 4 GB DDR RAM, ATI Radeon 9600, Apple Studio Display 17", HP S2031 20".
I do recommend iMovie 09 as it seems to perform okay, while offering a modern appeal. Good luck with your PowerPC Macs!
