I'm not seeing this. The only freezes I am seeing are in the linux emulation and audio (Skype and Flash) on 64bit. I am running 8.2 64bit, a GeForce GTX 460, and I switched to the 270.18 driver yesterday. 260.19.36 is the official release and I am not sure that you have tried that. Try the two different drivers and see what happens. From there, let's see what things you are doing differently from me.
