I'm not sure, if the new core will be much better than the last. My Sandybridge is running @ 4.7 GHz for years now. If you have single-threaded applications, as most are, there is no advantage.
The problem is, that intel could do far better, but there are no competitors, since amd was crushed. But let's see the oc-results later this year. Buying this at this price is a no-go. By the way, good posts :-)
