OP, have you ever installed a CPU before? It is pretty straight forward, but can be a daunting task for a first timer...It can easily be done by reading the installation instructions or finding how to articles on the internet.
You also might need to flash your motherboard BIOS if your current one doesn't support the CPU you want to upgrade to. Check the motherboard specs on the website (also, the most current BIOS downloads can be found there). Again, this is a straight forward task but can be intimidating to someone who hasn't done it before, especially since there is a small chance you could brick your motherboard if not done properly.
The only reason I post this is because you asked if it upgrading is possible, implying that you might not be familiar with this process...
