Same here with i7 CPU 16GB RAM and GTX770.
Trying many Settings, trying other Drivers, disable AV Software, updating System. Some crahes after 5-10 Minutes of playing.
Other Games running fine and without any problems.
Graphics to minimum -> crashes
Postgr. to minimum -> crashes
Windowmode option all trying -> crashes
uninstall AVAST -> crashes
Update drivers / or roll back -> crashes
with / without VSYNC -> crashes
Limited / Unlimited FPS -> crashes
At minimum Settings, GPU Load ist 99%, i think, the graphics is the problem.
Trying smash PC through window.... maybe later ;-)
