In another thread I've asked about buying used Apple equipment. Here I'd like to ask whether or not such a setup would have any problem running Aperture and CS2 (which is what I currently run). At the moment, I'm using this two applications on the iMac in my sig. I need more horsepower...especially for Aperture which just chokes sometimes. I cannot afford a new MacPro. So, I was thinking of buying a Power Mac G5. Preferably something with more than one core, and more than 2 GB of RAM. If I bought something like a dual 2.0 GHz machine with 2+ GB of RAM, would this keep Aperture from choking? Given my current setup, do you think that the RAM is the issue...or is it processor and graphics card and all of that? Any thoughts welcome...thanks!
