Probably not.... But, you will be giving one more sale to Intel, which will help to let them continue with the trend. Game programmers will continue to NOT optimise the games for multi threaded environments.
Everybody has different needs and everybody should buy what suits themselves the most. Advising you on whether you will see any difference in gaming performance or not will be a pure speculation on my part given that coffee lake is not around yet.
What I can tell you is that some people advised my to get 8 GB RAM as they think that I will not need 16GB most likely. I still went with 16GB. And guess what. A simple game like GTA V in single player makes my computer use 10 GB RAM. Does it happen with people who have 8GB RAM? No. But they lose those frames. Average frame rates dont matter. What really matters is the minimum. And our system should be built to target that. This RAM example is an analogy. May or may not be applicable to 6C/6T vs. 6C/12T. Will Coffee lake beat Ryzen? Who knows. But will they ever beat it at minimum frame rates? Not likely.
Anyhow, it was just supposed to be a rant. Personally, I go for AMD all the time as I like supporting the underdogs when I can. Just to give them a small help from my side to keep them afloat which in turn helps the competition live. Same reason, I always buy AMD graphics card (4870 > 7850 > R9 270x). This time time I had to buy a gtx 1060 because of all those miners and also because AMD didnt need my help this time, given, all their cards are selling.
This has gone too off topic, unfortunately, sorry.
TLDR; I was in your situation till 25 days ago. I did months of research for building the beautiful PC that I now have. I scratched my head, pulled my hair and ended up buying a Ryzen 5 1600 system which I was anyway thinking to get at the beginning. lol. You will also go through the same and its good that you will. I learned a lot during my time and so will you. Eventually, you will realize that whatever you build will be beautiful and serve your needs whether it is AMD or Intel. Good luck building your monster.
