So heres the deal, right now I have a G5 iMac with 1.5 gigs of ram. It a great computer don't get me wrong but when it comes to demanding applications its heavily lacking in performance. My interest and skill in photography grows daily and its something that I would like to do professionally. I use Aperture and most of the Adobe Creative Suite and my iMac struggles greatly to perform tasks and is impossible to work with when multiple applications like that are open. I shoot primarily in RAW so I'm really looking for more internal hard-drive space as well. I know that a Mac-Pro would be right up my alley, but financially its a burden. I was just wondering what serious hobbyist's and professionals setups were like here on macrumors.
