[QUOTE="technologist, post: 469771, member: 4134"] Yup. It depends on the program. Some programs require more memory than others. And most programs require more memory when working with larger files (for example, a high-resolution image in Photoshop with thirty layers will cause Photoshop to require more memory than a small GIF you copied off of the web. It does, up to a point. I guarantee your Mac would do everything slower if you removed all but, say 256MB of your RAM. :) But there is a point at which you have "enough" memory for what you're doing...and beyond that amount, adding more won't speed things up.Maybe. In Photoshop's case, it depends, mostly, on the size of the file you're working with, as I mentioned above. Well... 1. The clock rate of the CPU(s) 2. The amount of RAM 3. The number of CPUs and CPU cores 4. The seek time and transfer rate of the hard disk(s) 5. The speed of the front-side bus that connects the CPU and memory 6. The amount, type, and speed of cache memory available to the CPU ... I could go on, but the real answer is, "A lot of things." Keep in mind one thing: your memory upgrade will eventually pay off. Newer software, higher-resolution images, and changes in the way you will use your computer in the future will take advantage of that RAM. At the moment, you may have more than you can use...but you'll find a way to use it sooner or later, I'm sure. [/QUOTE]
