IMHO, drivers sometimes give a small fps benefit but mainly stability improvements are the most important, and that is what I`ve experienced most of all over the years. Currently on 436.02 WHQL.
Not always the case because I just saw a YouTube video where someone bench tested a game and the latest drivers were worse then the previous driver. For some reason he got 3fps less with the latest driver in the game called "The Division".
I also found the last driver that included Nvidia 3D vision made my 3D videos stutter, so I had to choose an older driver to stop this happening.
