Please carefully read Activity Monitor to read System Memory and determine how much RAM is being used and report back with what you find, you may only need to upgrade the RAM.
However have you done any troubleshooting such as restarting in Safe Mode to clear some caches or a SMC reset or even just restarting the computer?
