Yes these are nice drivers, but there seems to be a problem with them. there's a bug that shows an increase in temperature in 6800 series cards. It shows about a 10 degree temp increase. on your gpu. I've installed these drivers and sure enough it shows an increase of about 10 degrees. Some people are saying it's an actual increase while others are saying it the drivers showing the wrong temp. You can read all about it here
www.guru3d.com check your gpu temp before installing these drivers so you can compare.
