I need suggestion for a photo editing rig.

No real budget, I aim to save as much as money as possible


Lightroom benefits the most from a fast clockspeed, so I guess i5 is the best bet. I do not however, know how to OC. Some sellers do provide OCing service right? Which OC's better on air (I am willing to allocate budget on 3rd party cooler), an i5 or i7? is it worth it going to K series?

Other than that:
8gb RAM
2TB hd

already have an SSD, keyboard mouse. dont need monitor and speakers too.

I dont game, so no need for GPU.

Suggestions please.
