Is my MOBO broken?

[ItsSpicy]

Hi. So this is my first time on Toms Hardware, and that's because i have a problem that just wont go away, so i hope for some help.
So, playing games is something i do from time to time with friends or just on the weekends. But i'm having some really serious problems with my framerates, wich can go from 120+ down to 30 and 25. ( It was significantly worse before i upgraded my CPU, i will explain.) And this kept on happening, even after i upgraded my CPU from the FX-4100 to FX-8350, and upgrading my ram from 4GB to 16GB. Before i Upgraded, the framerates could drop below 15 FPS, which was horrible.
I was aware that the AMD FX-4100 really couldn't feed my GTX 760 OC DCII, which i bought after a faulty GTX 550Ti, so i decided to upgrade that, alongside a new cooler for the CPU.
The framedrops mainly occure when playing Battlefield 3, Battlefield 4, Battlefield Harline, Titanfall and Metro: 2033. It's really frustrating because i've spent alot of money on this, just to play BF3/BF4/BFH with my friends without any problems. Weird thing is that neither of the Mass Effect Games seem to have any problem, and i'm constantly pushing 60+ FPS...

After upgrading almost every vital and most believable problem, i'm starting to wonder wether my MOBO is broken?

My Specs:

AMD FX 8350 @ 4.0 Ghz
ASUS M5A78l- LE MOBO
Crucial Ballistix 16GB Ram @ 1600MHz
ASUS GeForce GTX 760 DirectCU II OC

If anyone has a clue on what the problem is, i'd appreciate it alot.

Your motherboard is the problem, it's not suitable for 125W chips. It's not broken, but it's just not good enough for high TDP chips, the VRMs and power phases are not good enough. Also, what PSU do you have?

@MeteorsRaining are you sure? According to the retailers who've built my PC in the first place assured me that it'd hold.
And, according to ASUS Website, the CPU is supported:http://www.asus.com/se/Motherboards/M5A78L_LE/HelpDesk_CPU/
I made sure to do my research before buying it, and everyone pointed me to this chip with my setup.

I'm quite sure. This is the AMD motherboards' VRM database:

http://www.overclock.net/t/946407/amd-motherboards-vrm-info-database

It's not recommended to use with 125W chips, see the note.

Here is a thread from OCN, "ASUS M5A78L-M/LE/LX ; M4A78LT-M/LE/LX Owners club!":

I run the LE version of the M5A78L-M and i gotta say, is pretty damn good for the price. Sure, it may not have support for 125W processors or packed to the frills with revolutionary game-changing features such as debugging LEDs or even a physical OC switch for that matter but it gets the job done and is a beastly little overclocker.

The ATX version may have got 125W TDP chip support, but it still uses a crappy 3+1 power phase design, I wouldn't use FX 6 with it, let alone FX 8.

Oh, okay.. I see. This will complicate some things in the future probably. Could you recommend any good motherboards for my GPU, CPU and RAM?
If so, that'd be really appreciated, and i'd like to keep the budget between 50-90 Euros.
And, perhaps you know how the transfer between programs such as DAWs, product keys and those things will be affected by the transfer?

Thanks for your help Meteors, in any case.

This would be a great motherboard for the price (I wasn't sure where in Europe you reside, so I've selected Dutch for reference):

Motherboard: Gigabyte GA-970A-UD3P ATX AM3+ Motherboard (€85.41 @ Home of Hardware DE)

Or you can select any Tier 1 Class A board from 970 chipset list, as per the price:

Or any Tier 1 or 2 board from 990FX chipset list, as per the price:
