This is also similar to mine, except the only thing that freezes is my game (I am running in full-screen windowed mode), so I can still alt tab out. Sometimes however, my whole screen goes black while the sound still plays and I'll get the driver has recovered error, but other times the game just becomes unresponsive but the audio will continue. The crashes/freezes seem to have gotten more frequent since last patch, I'm running it on a gtx 650 TI on 326.80.
