I've got a GeForce 6800 GT and use the 75.90 drivers from
http://www.guru3d.com/ and have never experienced any of the problems you guys have... I did extensive testing with a lot of drivers comparing my results with 3dmark and noticed that the 75.90 drivers were used probably 8 to 1 compared to other drivers using the same card in the highest score range. this was a while back that I did this but I stuck with these drivers because they gave ne the Best results and if it aint broke I don't fix it.
also I have been using the 3d fix with the SP2 fix and run the game 1600 X 1200 no problems
