<p>I purchased my student sons 2008 iMac and subscribed to the CC photography bundle. This plus a nice D7000 and two decent lenses came to a total of $1000. The iMac only has 4Gb RAM and a 200Gb hard drive. I am massaging and processing up to 16Mb TIF files and I have no problem. Before I was using a Sony notebook which had only 3Gb RAM and that was fine for me also. <br>
Maybe the CC version of PS and LR are less computer resource hungry. That would make sense as PS6 was pretty monolithic. I saw a response from someone who is using 32Gb RAM. Why? The performance of the computer will always be limited to the clock speed across the Bus where the app interacts with the computers memory and hard drive storage.<br>
After giving me the iMac on which he also used World of Warcraft, he built his own tower with 16Gb RAM with quad processors and some mega video card with fans etc. Compared to his old iMac, its really not that seriously faster. Maybe 50%. I can live with and save $5k.<br>
Perhaps there is computer performance envy like there is digital camera envy at play. I ran a utility which measures RAM usage. With iOS, PS and LR CC and Perfectly Clear, its at 70% of 4Gb. My recommendation is to put tech lust to one side and instead get out there and do whats important...producing nice images which tell a story. </p>
