Genuine Nvidea vs. made under licence

When I selected an Nvidea adapter from the SW approved list Idid not notice any caution about genuine vs. made under licence.

I did not understand why Leadtek's name was on the box and afterpoking around for a driver that would work I concluded that Leadtekwas one of two companies that make Nvidea adapters under licenceand write their own drivers with different names from the genuinedriver.

Has my ignorance caused me disadvantage as a SW 2009 user?
