Right now I have a Mac mini (see sig) and I thought about doing some moderate-heavy photo editing (learning how to really use Photoshop and Aperture). When I was using Aperture or Photoshop, my mini seemed like it was a little laggy for doing the graphics. I may be coming upon the opportunity to get a PM G5 soon (Not sure what specs it would be at the moment, but it would be <$200 and fully upgraded, but not sure what Rev./ model it is). With my mini, should I even bother with the G5, or should I wait a while and eventually just get a Mac Pro or iMac at some point?
