The best stress test is a real-world test. Say a Sony Vegas render then watch those temps. I think some CPU burn-in test are far too beyond what goes on in the real-world and would damage it. If it pass the test then OK but the chip really significantly degraded if it's at the upper-limit.
If it can past say a 10 minute render then it's good. Gaming shouldn't tax the CPU like a render. A render is a more real-world test.
