Since removing CCC, I went about a week without freezing. I got a little confidence in my machine and tried watching netflix while playing on my 2nd monitor. Froze within 10 minutes. I haven't locked up without dual monitors running.
I also used a driver cleaner to clear out any remnants of older drivers from my machine. I just bought my 7950 last spring, but before then I was using another Radeon HD. It took about 45 minutes to clear all old driver files from my machine, then 10 minutes to reinstall. http://phyxion.net/item/driver-sweeper.html
<-- this is what I used.
I played for about 10 hours over the weekend and didn't freeze once.
