I have an intel core2duo e5400 with 4gb ram running win7 home premium x64. It's an always-on machine, and I've noticed that if I, for example, go to open chrome from the taskbar (running in the background) the hard drive grinds like anything for a few minutes before I'm actually able to go ahead and use chrome. My ram usage is always above 70%, and I realize that multiple apps would be reducing performance. Just wondering, would adding another 2 or 4gb of ram improve my being able to run multiple apps and being able to switch quickly between them, even though they've been running without being used for a while?
