I have installed a laptop from MSI (CX61 G51-N1RAK19-CB8) with an i3 4000M, but it is often at 100% performance. Which CPU could be considered as an upgrade?

I would have thought of an i5 now, but unfortunately I don't know which processors would fit or what is important.

CPU is soldered, there's nothing upgrades
