CPU Throttling, Intel Core i5-3350P?

So I recently broke down and built myself a gaming pc rig,
SPECS:
Gtx 750ti
8GB Ballistics Ram
Intel Core i5-3350P

My PC has never ran like I've wanted to, I get skips in frames on games, I'm sure it is CPU Throttling, But I did extensive research on my CPU before I purchased it, and it had nothing but wonderful reviews from everywhere, the fps spikes even occur in Starbound, Minecraft, Garry's Mod, etc. Very easy to run games! It is ridiculous, I know it is not my GPU, it runs just fine on games that take less CPU usage, I'm wondering, did I just get a hold of a bad CPU or is the CPU just a **** CPU, I did pay $229 on it. Also if you have any fixes for CPU throttling to share, that would be great.

Edit: I just used a program that pushed my CPU to the limit and it measured the throttle, etc, and it showed no throttling of the CPU in the stress test, not really sure if that is to bu trusted or not. Still any suggestions? I used, AIDA64 Extreme to stress test!

Turn off the overclocking. There's no need for that and it's probably causing the issues.
