Nvidia has open-sourced the kernel module "driver", which recently have been declared stable enough for general consumption.
But the kernel-mode driver is only a small part of what you would call the graphics card driver, and the bulk of it is still very much a proprietary blob.
The true open source driver for NV cards is Noveau[1] which works ok with older cards but is slow to support newest cards and features. Performance, power mgmt and hw acceleration are usually worse or not working at all compared to the official drivers.
