If you've bought an Nvidia-based card in the past three years (and who hasn't?) you've probably noticed the dozens upon dozens of different “brand names” that vendors will give to the cards. Nvidia's resellers have been a strong point for them in the past, but now not so much. It seems that Nvidia is tiring of so many different brand names on the market for the same type of card, and as such as planning to cut off many partners.
In particular, they are dropping “smaller” partners, seeking to make the market for their cards less diluted. It's easy to see the advantage there. You won't be faced with 25 different iterations of the same GPU when looking to buy, and it would make different cards easier to compare, relatively. But how large will the difference be? Nvidia didn't say, nor did they say which partners were getting the axe.
