GPU's, even the GTX 480 have an absolute thermal limit before they start to break down, i think its over 100c, but not far over, even then, solder and glues will start to fail in the high 90's, by the time you get to that point you will already see the effects of that on your screen.
AMD's GPU's are set to start thermal throttling at 85c, it goes in stages from the boost overclock to its base clock, then to 500Mhz and then to 300Mhz, it will keep going up and down to keep it under 85c, if it stays over 85c and can't get under it it will just run at 300Mhz, GPU-Z has this one running at 93c, NOT - A - CHANCE with those scores.
I said the first time when these Chinese scores surfaced, the ones where the R9 290X beat the Titan in FireStrike somewhere in this thread.... that i will believe it when i see it in real reviews.
This one, with those temperatures is almost certainly bogus.
