I'm currently using handbrake and my cpu is at 76, last night however i was using handbrake, neooffice, transmission, firefox, and mail (plus more maybe)....it was up at 90+ for some time and didn't like that
I had that screen which informs you all is lost, and you must reboot...then when i rebooted my xp partition was not there!
I got slightly worried since all my uni work is on the xp partition (but backed up) but eventually it came back.
So, back on topic, your 83 is fine, and besides, if your computer blows up due to using photoshop it's a warranty thing, as you're only doing what the computer was designed to do!!
p.s. any statement that's followed by a winking smiley is always a joke. And any sentence the begins with the phrase "Seriously though," also means that the preceding sentence was a joke.
What a profound explanation! It should be made into a sticky!!
<--- See what I did there!?
