Howdy all, So, my wife and I have a budding photography business. As we've become busier and busier, our old system of working with RAW images has become unmanageable. Moving to an application like Aperture or Lightroom has become preferable. Because I'm pretty much an Apple fanboy, we chose Aperture. However, currently we're running Aperture on the iMac in my sig. The 1.8 GHz G5 and 1 GB of RAM just don't cut it. Especially when using Aperture and Photoshop in conjunction. The logical step would be to move up to a Mac Pro...but resources are just too stretched at the moment to throw down $3000 (the cost of the Mac Pro + a decent monitor). So, I began to think that a PowerMac G5, loaded with RAM and a two or four processors could do the job for a lot less cash. Questions: (a) What configuration would I need to run Aperture and Adobe CS2 fluidly? (note that I'm only looking at computers at the moment...I've got scratch disks and stuff like that taken care of) (b) Does anyone know of any online retailers that are reputable and deal with older model macs? (c) Is eBay a crap shoot? Any advice is welcome... Thanks!
