recently I have found that when I am operating PS CS5, I have hit a major slow down when trying to run another application, Just wondering if upgrading to 8GB ram (800Mhz ) from 4GB (1066 Mhz) will make a difference, The processor is an Intel(R) Core (TM)2 Quad CPU q6600 @ 2.40Ghz. I could upgrade the processor and MB, but I rally do not want to have to do that at this time.
