Yeah, Prime is kind of special in its ability to send current down every circuit in a cpu... it's definitely a worst case scenario. As yet, I've yet to see mine pass 50 in games, but it Primes at 67. Even priming on a single thread will push it to 50 - possibly because XFR kicks in and slams the volts up to 1.45 or so... On the whole, it's going to be interesting to see whether the X chips actually last through their warranties!
(That said, with a new era of competition in CPU space, who really expects to keep their new Ryzen for 3 years?)
