X crashes with rhel 6.5 and nvidia quadro 6000

Our system has a somewhat unique configuration where we have a quadro 6000 being used to connect a monitor and we have two Tesla K20xm for computing purposes (no display). I have been unable to get our system to be stable and have tried different nvidia drivers. I am trying to use 304.1170 which is recommended for the Quadro 6000 and the 319.76 which is recommended for the Tesla’s. These (as well as some older versions) always make our system crash. I have an identical system that is still using the nouveau driver and it is very stable. I would like to know what the best driver is for our configuration. The crashes are most frequent when I use firefox which sometimes crashes immediately. Any help would be great. Thanks.
