80-85c sounds very reasonable for the JZ. 92-93c is the thermal limit which will induce throttling. But the asus (having a beast/aka/880m) should run warm, but should not hit the 90c mark. Even benching or anything it should never get to 90c. On contrast, the msi with 880m runs pretty constant at the 92c and throttling, and well I guess that's how it was designed as every user ive spoken with or read about has stated just that fact.
