Why would the registry files be any different than the stock blower style cooler? It's the exact same card.. It baffles me how people think changing the outside cooler turns it into a completely different card. If the core and memory are the same (from same manufacturer), the card will perform exactly the same (apart from better thermals of course)...
FWIW, while I don't know anything about the Nitro, the MSI Air Boost (which looks the same as the reference cards) does not perform the same. It seems to have Hynix memory (according to GPU-Z), and I was never able to get it to work even remotely well.
