970 low/unstable gpu usage causing stuttering/low/unstable fps issues

[korvfinger]

Hi guys, I really need your help this time.

Okay here we go; this is my current rig

 

i5 4690k (OC 4.0ghz)

MSI 280X (not OC atm) not using these at the same time (GeForce GTX 970)

16gb ram

ASRock z97 Anniversary (Motherboard)

G550M Coolermaster (PSU)

 

 

I just bought an 970 to upgrade my rig. The thing is, I had GPU usage drops and low usage causing stuttering and low fps with the 970. Thought that maybe it was something wrong with just that card, got another one and got the same problems.

 

(Yes I uninstalled the display drivers with DDU both times)

 

The 970 never uses 100% of my power supply so it shouldn't be that either and people say the G550M is enough for my setup but I don't know anymore.

 

I decided that I'll return that one and go back to my 280X and just chill for a bit since I've been trying to fix it for days.

Now when I put in my old card it overheats with low fan-rpm and causing the coreclock to lock at 500mhz.

 

I'm all out of ideas guys please help me.

 

EDIT: I've also done a clean install of windows 8.1 and tried both cards/drivers and still not getting it to work.

Delete AMD drivers

Delete AMD drivers

I've have done that already "(Yes I uninstalled the display drivers with DDU both times)".

But I hear people saying that the new AMD Crimson Drivers are causing problems for people.

Can anyone confirm this and in that case, do anyone know where to get old drivers?
