I had the same sort of issues with a 7600GT, and ended up taking it back to
the place I got it from to exchange it for an ATI card. It too didn't have
abnormally high temps, but my understanding is that it's not just the GPU
that can overheat. Other components on the PCB are also affected, and
there's no way to monitor their temperature.
15 minutes after getting my new card home, I was back in Oblivion, with nary
a lockup or BSOD in site. Well, besides the known blowing up as you exit
the game and stuff...
I'd send it back.
