i use AMD overdrive precision boost thing on (i have OC mode always ON anyways)...
My GPU is stock around 68°c (154°F) (and playing)
But the worst is my laptop... i added a 2 fan, something like this:

it is open and the fan is blowing air towards the heat pipes, ram, chipset, etc...
with a full CPU + GPU load temperatures are around
CPU: 81°(177°F)
GPU:74°(165°F)
MB:76°(165°F)
without the 2 fan: 90°~
HOT!!!
