you will see my card has a serious problem . However if I don't install the nvidia driver then I got no problem (no pixel problem)
I have tried:
1. make sure my bios is running the latest version
2. tested on both windows 7 sp1 64 bit and 8 64 bit. Also I have all the windows updates installed
3. tried all available drivers: 320.18 320.14 320.00 and 314.22
and it's still not working
dell xps 8500 (0NW73C motherboard)

I REALLY hate to say it but that is likely to be a bad card.
since its a boost edition, i would suggest downclocking it a bit. And if that doesn't work then you may have to get a new one.
I have a gtx 680 from zotac and they give a warranty so I'm sure they would give you a new one.
I may have the same power supply as you by the way, so that shouldn't be the issue.
