I have the Early 2006 iMac Core Duo (not Core Duo 2) and I'm aware that it's almost a dinosaur in computer age, but I'm here to seek help in acceleration for Photoshop. This model can't take more than 2GB RAM unfortunately (late 2006 models can take more) and I have plenty of hard disk space (87GB left on a 250GB drive) but it's nothing but the spinning beach ball no matter what I do. My Photoshop files are usually really big so please don't recommend making them smaller, outputting into separate files, etc. I would appreciate some solid, practical acceleration tips maybe regarding an external scratch disk or specific Photoshop settings, stuff like that, before I lose my mind waiting for every damn process or save to finish. I lose hours a week and I'm unable to get a new Mac at this time.
Thanks, Scott, the freaked out freelancer :/
