I have tried the latest forceware drivers but they are totally BETA in a big way and did not install for me, I have been watching the "Ultra" modified drivers carefully the 86 gen drivers are well tested and well liked in the OC community. The "Sedona"beta works great for me and I can reccommend, although the new control panel does not work but thats the only "bug" that I have incurred...
I prefer the old style control panel anyways
