Benchmark Reviews posted a comparison between NVIDIA Forceware 175.16 and 175.19

Most people would think that when NVIDIA, who is the world-class leader in graphics technology, releases a new driver to the public that performance would either remain the same with some stability improvements, or that both performance and stability would increase. As a hardware enthusiast for over a decade, I know that this isn't true. Very recently NVIDIA updated their Forceware driver from version 175.16 to 175.19. Anyone familiar with their updates would agree that the version number difference is so small that it would suggest nothing has really changed. But did NVIDIA take two steps backward instead? Benchmark Reviews offers this small article to demonstrate what we discovered while testing the GeForce 9800 GTX and 9800 GX2 video cards.
