I'm not sure if this information is accessible through nvidia's official APIs.
It would be very usefull, with at least the brand name : GPU-Z manages to display brands.
Probably it uses it's own database to do so.
ccminer can also display the vendor names
maybe this link is helpful:
http://docs.nvidia.com/gameworks/content/gameworkslibrary/coresdk/nvapi/structNV__CHIPSET__INFO__v2.htmlNV_CHIPSET_INFO_v2::szVendorName or NvU32 NV_CHIPSET_INFO_v2::vendorId ?
i would also really appreciate if you coud add vendor info - would be helpfull in mixed setups
