    As far as I know the Activity Monitor anyway always say the RAM is full because it cache all, thats right?
    So how can I know when it will be useful to upgrade my 8GB RAM?

    It is quite normal for all of your memory to be in use by OS X. It does not mean that you are running out of memory or that it is maxed out. OS X will manage all available memory, making it available to apps on an as-needed basis. Refer to the following Apple support article for more information on how to understand your Activity Monitor readings.
