So, I'm in the midst of building a new pc and decided to wait for Coffee Lake.
This is primarily a gaming rig with maybe a couple programs running in the background (youtube, Chrome, nothing major)

i7-8700K - 6 core / 12 thread (I assume 12 due to HT)
i5-8600K - 6 core / 6 thread (no HT)

Will going from 6 threads to 12 benefit gaming in a meaningful way?

I'm thinking 8600K is best bet choice.

I decided 6 cores is going to be a good bet (or at least try to cover my butt bet) for best performance in AAA titles coming for the next 4-5 years.

Edit: Maybe to put a finer point on my question, for gaming does going up from 6 to 12 threads make much difference if both have 6 physical cores?

I would say there is enough information in existence to make a judgement. If the 7700k is better for games than a R7-1700/1800/1800x than the 8700k will be slightly better than that. It will also bring in some of the advantages of the extra cores. For the money, I doubt it can be beaten (unless the motherboards or processors get jacked up in price badly)

Charts showing 4C/8T vs 6C/12T of the same architecture already exist, so the scaling should be similar on titles that even bother to take advantage. (Haswell/Devil's Canyon vs Haswell-E)

Only real wildcard will be the i5 with 6 cores. I imagine it will be the best bang for the buck, but then it usually is. Should do well in games compared to a Ryzen 5.

No. Hyperthreading at best will be like having 1 extra core. It's not worth it for this generation of CPU's. Now considering that the quad core CPU was just starting to become obsolete for gaming hyperthreading is a great help on a quad core cpu. A 6 core CPU doesn't need that little extra help though. Probably won't need it for a while.
