I just installed Nvidia's graphic driver 180.84 and I must say, this is one of the best Nvidia drivers to come out, never mind the fact that this is a beta version. Contrast has been bumped up and the primary colors stand out with sheer clarity. The image quality of this graphic driver is so superb that it's still easy to spot the minute shotgun shells in 3dMark 2001 SE's (a freeware benchmark software) "Lobby" sequence.
For the benchmark test results of the Nvidia GeForce 180.84 see my "Nvidia Graphic Drivers Benchmark Tests" article.
