My problems were:

  • Overheating
  • Poor performance when overheating
  • Overheating

Frequently the temperature as reported by system monitor would register around 95C degrees, which is uncomfortably warm to both the lap and hands. I did a lot of probing around and eventually wrote a script to just detect when the graphics card was in a wierd state

After a lot of mailing list and Google research (months, not days or hours) I finally stumbled on this tidbit on the ArchWiki
