AFAIK, there are no reset issues for Kepler and newer cards, including the 660. Fermi cards always seem to cause problems, but I don't necessarily think it's reset related. Reset problems on nvidia are more likely a result of trying to assign the primary host graphics or getting the card into a bad state with host graphics drivers. I have a GTX660, it doesn't get used often for this purpose but IIRC, it works just fine.
