In this thread at the TWC, the OP links to a thread at the Nvidia forums and the official CA .com site.
It seems that the pre 100.x drivers solve this problem. This might make sense actually because I had this problem on a 7300GT with the latest drivers. Installing the older drivers and changing a few setting eliminated it.
[speculation]In short this issue may not be the card at all, but Nvidia drivers between certain versions.[/speculation]
