I doubt "Bad commands" have anything to do with GPU temp. If you start seeing odd things in your monitor (stripes, odd colors, etc), then it's probably a temp issue.
For those that don't know, this is an issue with the Frostbite engine itself. It is one of the many issues that Bioware failed to correct before developing DA:I. Battlefield 4 had the exact issue and it has been corrected. You can read about it here: http://answers.ea.com/t5/Battlefield-4/BF4-DirectX-Error-GetDeviceRemovedReason/td-p/1915085
I uninstalled because the patch 5 beta greatly increased the number of crashes on my end. In tell Bioware fixes the issue I'm done with DA:I and Bioware/EA.
