Seems like it wasn't a very profitable business. Not only did it bury 3dfx, but all the IHVs that nvidia built its lifeblood off are gone. The only current companies that I remember being arouund in 2000 that make their own boards are ATI and Matrox, and Matrox pulled out of the 3d graphics market and ATI has given Sapphire free reign.
Most of the companies nowadays have either risen from the ashes of the old companies (I hear XFX came from the remains of STB and 3dfx), or come in from other, similarly cutthroat low margin markets. PNY makes memory, and there's quite a few motherboard makers getting involved.
3dfx was the most notable name to go down during that time period, but it seems that the graphics board makers as a whole were unprofitable. Yet despite most of nvidia's partners going out of business, they were easily able to find new partners to sell chips, and have remained profitable year after year.
