Having said that, what's the reason?
If it feels sluggish, and has an HDD, then possibly you can swap that for an SSD.
I can't tell though since there seems to be many different configuration options for that model.
*You can tell if the CPU is the problem by opening Task Manager (right-click Start.. ). Performance-> CPU-> (right-click and change to show more than one graph if just once CPU graph).
Any time the CPU is the bottleneck you should see at least one graph hit 100% usage usually.
