Drastic CPU spikes in every game

Hello everyone,
I'm new to this forum so I excuse any mistakes I may make.
I'll start of from the ultimate begining of my problem :

I've upgraded my PC rig a couple of days ago and made these changes :
-went from an AMD fx-4100 to an AMD fx-8350
-from a gtx 550ti to an MSI N770 2GB
-from a 500W Corsair to a 750W Corsair

Everything seemed to be running fine until sudden FPS stuttering and dropping appeared in BF4. I originally thought it was because of the game itself but I tested Tomb Raider and Far Cry 3 and every single game suffering from the same issue.
I decided to go into my bios and disable cool'n'quiet and followed many tutorials I googled without any success.
I tried increasing the games' priorities and installing the lasted drivers without the slightest amelioration.
I checked my temps and they are fine (between 55-62°C)
My CPU is by no means overclocked and nor are any of my other components...

I had some issues with the stock AMD fan (7500 RPM in game !) so I put my old one back on (back down to 3500 RPM).

At this point you may be thinking it may not be the CPU affecting the games only I checked my CPU's frequency and whenever the game's fps spikes, my frequency goes from 4000Mhz to 2600Mhz and then goes back up to 4000Mhz.

On top of that, I opened the CPU and GPU graph in BF4 to see what was happening during these spikes.
This is what happens :

Now this part becomes interesting : I decided to replace my new processor with my old one (fx4100) even though I 100% knew it would bottleneck it... It did bottleneck and i did loose around 20 fps but the spikes and fps drops were not present. I thought it was a coincidence but after playing a couple of other games I figured that my new CPU was having issues...

It is very random and makes it impossible to play, I've been stuck with this never-ending nightmare for a couple of days now and wasted my time desperately trying to solve it... I could really need some help.
Thank you.

My PC rig :

AMD FX-8350
MSI n770 (2GB) Lightening
PSU : 750W Corsair (Modular)
Ram : 8GB (two sticks)
Motherboard : Asrock 960GM-GS3 FX
1TB HHD Hard Drive

That would explain why my old processor worked !! Because it was supported by the motherboard while this one isn't !
Thank you very much boncedk, I'll try to upgrade to an Asrock 990Fx Extreme4.
