Just wanted to point out a bit of news for everyone. Some of the most recent (not sure if I have the absolute most recent) NVIDIA drivers have seemed to get better. I personally have an SLi set-up and before the 400 series came out my system would constantly crash. Lately though I've noticed no crashes. So if your running SLi 200 series rest assured the new drivers, at least for me, have gotten better.
I will however say that I have not tested out SLI AA. That was the biggest crasher in games. I love SLi AA because it is much faster. I will try it out tonight and report back.
