Recently purchased an iMac G5 with the config found in my sig. With 256MB of RAM, I find the iMac to be apallingly slow. Has anyone else found this? I'm upgrading the RAM ASAP (crucial), but I just wanted to know if maybe there was a larger problem. My iBook G4 800mHz which has 640MB runs a lot smoother than the iMac. If this is the way it is, I'm disappointed that Apple would even sell the iMac with only 256MB RAM.
