Nos - i think their fantastic. Heres a blurb i wrote on them on a BF:2 website.
Just wanted to let anyone interested know that i found a fantastic driver for BF:2. I downloaded the 87.25 (modified z-tweaked) drivers from guru3d. People on their fourms were saying they got 10 to 15% more FPS during the game. I must admit after using these i hardly get any lag, or slow down even when there lots of bodies around and complete chaos. The 87.25 driver was originally for Oblivion, but has been modifed to be a better gaming driver. Anyone who wants to take a look at it here's the link. Note - these are for gamers who want an increase in FPS and performance and are not for people wanting to have the highest settings possible because graphicly it dumbs the game down. I also read that you are unable to use AA in your graphics options when using these drivers.
Heres the link for the driver itself:
