Probably not to be honest - I suppose it depends on the other specs in your system, and if you are ok to spend money for a small increase in performance.
You would notice an upgrade from 4GB to 8GB with the Vengeance RAM, if your system allows it (I assume it would), but swapping the original 4GB for the newer 4GB wouldn't yield major benefits (although granted, there would be an improvement, but again it depends on the system / what you are going to do with it - if you are just word processing and surfing the web, dont expect to see much)
