x11/nvidia-driver is the driver released by nvidia.  It doesn't work on 
architectures other than i386 and has some other limitations (breaks certain 
components of KDE4, for one other thing - see the 'black windows bug'.)  It 
does support 3d acceleration using the nvidia GPU, though.  

The x11-drivers/xf86-video-nv port is the open source Xorg driver for nvidia 
chipsets.  It doesn't support 3d acceleration using the GPU.  

Neither is a perfect solution, and the disparity has been an issue for years
