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!

EDIT: Totally forgot to add the specs...my bad :D here: http://pcpartpicker.com/p/E5mP

It's not the Video card it's those games, they are power hungry with all their graphics and high frame rates. You need at least 25% free disk space on the OS drive (partition).

Your video card is 3gb vram and has 3 fans, assuming that your model number is GV-R797TO-3GD, the card bus is PCIe 3.0

The power requiremnt is 600 watts, I'd go for a higher PSU maybe the 750 watts would be better.

There is nowhere on the site that tells you the cable requirement nor the images show the connectors. Very frustrating, it makes one assume that the power for the video card is coming through the motherboard.

Can you tell me what the cable requirement is for yor video card? Not even AMD knows!
