My computer has been running slowly lately, and I want to add some RAM to it to help speed it up. But my concern is that it is a Mac Pro 2 x 3 GHz Dual-Core Intel Xeon with 4 GB Memory purchased in 2007.
I'm wondering how much Ram I should add to this computer, given that it's a relatively older processor? At some point, does the extra RAM not make much difference if your processor is just older and slower?
I work on large image files, often 1GB files, often opening more than one at once in photoshop, while also having other applications open, like Lightroom, a web browser, and while also printing prints on my inkjet printer, etc.
