I've bought everything for this build except for the CPU and the PSU. Like an idiot I didn't factor the MIR and am short of money to complete the build. Now my two options to fit my budget are

A. Buy a refurbished version of PSU and keep the i3 4160.
B. Buy a new version of the PSU and downgrade to a G3258.

I'm building this PC for gaming, mainly to play CS: GO at higher FPS, preferably 120+. Which do you recommend I do?

I've already purchased all the parts except for CPU and PSU. But yeah I was leaning towards the G3258 and just overclocking. Thanks for your input

I have a microcenter near my area that has i3 4160 for 100$, so it'd actually be cheaper. And NCIXUS has it cheaper atm.
