I was wondering if I need a memory upgrade. Currently I use Windows 7 x64 with 4GB ram (DDR3) with a Radeon 4290 (built in graphic, eats about 500MB RAM). I use many programs at once (Adobe CS5.5, Outlook, etc.) but still from what I can tell from my desktop widget it uses about 70-80% RAM.
Is there a more efficient way to check memory usage while working on several programs?
Based on that, do you think I need a memory upgrade since it's not running 100%? I'm mainly asking because I don't work on very heavy graphics and wondering if after upgrade I would get a noticeable boost in performance.
