No new models of GPUs can be added to the GPUs.txt list until Pande Group fixes the update script problem that I emailed them about 2 days ago. GTX 1060 is enabled, but won't say GTX 1060 until this is fixed. It will only say GP106 [xxx] until fixed.
The AMD RX 4x0 models are also enabled already, but won't have proper naming either until this is fixed. Not a bug, just a feature.
