i still crash randomly, its a known issue with Uldah and Uldah merc house (in other cities also).
I noticed my server is always getting emergency maintenance also (Excalibur).
They also said in the most recent patch that they fixed aa couple of places where the game crashes so im sure SE is aware of the crashes ppl are experiencing.

I'm pretty sure at this point its not nvidia's fault. My 670 runs other games flawlessly, i just hope 2.0 works fine.
