Is this error due to my PSU?

Hey guys, I recently built my first computer which at first I was extremely pleased with. I got everything in except for my GPU and my computer was working great (besides the fact I couldn't run games, but that was without my GPU). So my Gigabyte Radeon HD 7970 comes in and it works great for about an hour. Then I begin getting the dreaded "Display Driver amdkmdap has stopped responding and has successfully recovered."

I have tried pretty much everything except returning any parts. I believe my problem is that my PSU. I have a Corsair CX600 Watt
PSU. Games like Far Cry 3 and Battlefield 3 crash within 2-3 minutes of gameplay. Other not as high graphical games run perfectly fine at max settings. I also just checked with MSI Afterburner and it showed on the games that I crash on it has about 99% GPU Usage. I just tried Chivalry and I think the max got to about 78% or something around there.

I need help and need to know if I should upgrade my PSU! Also if so, i was looking at the Corsair TX750 Watt PSU and was wondering if that would cover me.

Thanks!

    The CX600 is plenty enough for your build so I dont see that being the problem. The only thing I can think of now is doing reinstalling the CCC drivers again. Which im sure youve already tried ?
