What sort of tasks do you do on this PC? If you do any extensive gaming, I would, in my opinion, invest into a newer platform and CPU, something like an Intel Core i5-6400 + R9 380. This option would also remove the necessity for any sort of aftermarket cooling solution since it's not extensively OC'able (The i5-6400). If you say the CPU still satisfies your needs, then I would say go ahead with your lovely upgrade! Like others have said, that motherboard will allow for some pretty good overclocking on that 1100T
