I had the same issues with the ATI 9700 pro, went back to Catylst 2.2 drivers ( came with the card), increased my voltage to 1.6v to my AGP via bios, and disabled fastwrites.
System seems to be stable ( for the last week anyway ). I also found this post:

It's my understanding that ithere is a voltage/current issue with the AGP port. Any variation in current or voltage settings on the "edge" creates the problem. Those with PS around the 300/350 range are going to have current issues, and those with adequate supplies could have voltage issues. It's not just Granite bay Mobo's either. The Via chip set boys are have a bad time of it also.
I'm very comfortable with my system and power supply, but was surprized to find the voltage to my AGP port to be at 1.46v ( Asus probe).
Good luck with the new system. I'm sorry I didn't check the board sooner ( on a leave absence from AH ).
