I agree. The 6600K is probably a better value, but the 6700K offers supreme performance (for a hefty price premium).
If you plan to multitask like recording, streaming and gaming all at once, then you'll likely enjoy the extra performance offered by the 6700K. I love mine.
For me, getting a stable OC took forever on the 6700K, but that's probably because I'm used to overclocking AMD CPUs. I imagine that the process would go smoother for someone who's used to OC'ing Intel CPUs.
