Bench results or it didn't happen
So far I'm not seeing it. Still doesn't mean it won't happen, but look at how long it took for us to rise beyond the quad core for gaming - and even the benefit of 6c over 4c/8t is minimal at best. I would say its better to get a 6 core with potential to grab an extra 100-200 mhz or get similar with less costly cooling requirements and less need for a great chip. The only thing that may skew things in favor of the 8 core is the fact that the 9700K will be soldered.
