I have an Amilo PI3635 which I use for doing lots of InDesign/PhotoShop work. I tend to use this machine for running scripts that spend all day opening/modifying/manipulating PDFs or graphics files and then saving them back out. It runs pretty fast but I have a big job coming up and it would be good to know what is the best way of improving the performance of my machine for this sort of task. I don't know too much about hardware so am I best to expand memory or graphics card or what??!?!?!?
