As we can see from pool, x265 will probably keep it's gp. I like this bench, never killed any hardware on it, even when pushing my 7700k at 1.8v i killed it, but i'm pretty sure i was using less vcc, pll etc... voltages than top overclockers.
But i know x265 can really kill much more cpus than other benchs, so, as Scotty said, the limit will be our goal, and as havli said, it's our own risk.
