Weird graphics card/motherboard problems

I am in a spot of bother....

First of all my current specs:
Intel i7 6700k
MSI Z170A pro Carbon
HyperX DDR4 2x8 2133mhz
Asus Dcu2 GTX 670
Silverstone Strider 850W 80+ Silver

So allow me to paint a fairly vague picture. I have only just recently upgraded to the Intel Skylake Z170 platform from my old AMD 990FXA system. My original motherboard was an Asus Z170-AR, I had the system running fine with that board, games worked fine and I was amazed at how quick everything was, only problem was the onboard sound for the motherboard was faulty and I had to send it for RMA.

In the mean time I couldn't deal with the thought of being with out a computer, so I went out and got the new MSI board that recently came out, the MSI Z170A Pro Carbon. Did a new installation of Windows 8.1, installed the drivers and away I went. Though I started noticing problems with the system, after a small period of playing a game such as Dota 2 or Final Fantasy A Realm reborn my frames would drop to 15-20Fps in both games and the system would slow to a crawl even after I closed the games it would remain slow and rather unresponsive. So I opened up MSI afterburner, ran furmark and noticed it would peak out and hold a steady 100% usage, voltage, FB etc, then it would start fluctuating and gradually drop down. The FPS in furmark were dropping as well even though the temps were alright at 76 degree Celsius, eventually the system would start grinding to a hault, either being slow and terrible to use until I reboot, freezing, crashing or display driver crashes

Naturally the first thing I did was uninstall the Nvidia drivers and try installing a different version. I've tried 361.43, 361.75, 353.06 and even the latest 361.91. All of which were clean driver installs, it solved nothing.

Has my graphics card seen it's last days or is it related to the motherboard? Because the system was running fine on my Asus Z170-AR that was RMA'd, the system Primes fine for hours and memtest86 that I ran over night came up clean. Unfortunately I cannot provide any screenshots of afterburner during furmark as the system is pretty much unusable or crashes during or after it finishes.

Have you checked to see your RAM usage ? I once had that problem with my new PC, turned out it was a bugged install of the OS resulting in my RAM usage being over the roof, making processes and game performance to be very slow.

Thought I would do an update, a friend lent me his old GTX 570. Installed new drivers and tried furmark again and started a youtube video to pass the time, the system black screened but the video kept playing.

So I am thinking it's something to do with the motherboard or my powersupply. Though more swayed to motherboard as the system was fine with it's previous one.
