Well the game is pretty bad for that, crashes on me too occasionally. I managed to reduce the amount of crashing by running a bunch of stress tests on my system, and for me I determined that my RAM was just a little unstable. I bumped my DRAM voltage a tick and haven't had many issues since.
It does CTD here and there, but it's much better. So I'd suggest you check if you're totally stable.
Also do you have the latest GPU drivers?
About the drivers, I downloaded the latest beta drivers no issues as of yet not even minor artifacting which would happen occasionally. I have stress tested my system and all is stable, the only thing I don't like is the CPU temps get up to about 58c when playing bf3.
