If I might put my 2 cents in on this, it's SE's issue, I have an I7 3770k with a MSI GTX670 and get the crashes as well, but when i get it, it also locks up my intel chip monitoring system, I have noticed that both my gpu and cpu ramp up overload then no dx detected only in the bazaar areas, Both intercooled as well, niether ever above 35 C. Both also have self overclocking, which they both go to far at certain points, so it's not a gpu or driver issue, cause my CPU wouldn't be getting nuts, no biggy I just have to restart my monitoring back up. It's something with this engine and self clocking technology that's not meshing right. That's just my opinion I'm no tech.

They're making a new engine because they can't easily make changes (according to SE) I think this includes this bug. Hopefully 2.0 will be better, but doubt this will get addressed before that
