As others have said it's only the proprietary binary driver that doesn't support amd64 (nvidia are waiting for kernel changes). As well as the lack of 3d-support the nv driver has always seemed to me to be less efficient even on 2d. > If I choose a Nvidia based motherboard would I have to install the > i386 version of FreeBSD if I wanted to use the onboard graphics, in > which case to what extent would the overall performance suffer? It depends on the application, there are a few things like mp3 encoding that benefit, but generally the difference is small. It's more a matter of memory and address-space support - amd64 supports more. However i386 uses memory more efficiently if you have less than about 3.5 GB, and it avoids the overheads of running both 64 and 32 binaries (many desktop installations are not pure 64-bit).
