Just from reading, just pick up another 4gb stick(ram) from your local IT store. The more ram you have, the better in terms of, running multiple applications.

That's provided the MOBO supports the additional Ram, and/or the availability of slots. I'd check that prior to committing.

Although I've yet to find any significant benefit, provided the device supports It and It Is In fact memory-related, you can try using ReadyBoost.
