Looks like many people decide to switch to AMD.
He done fantastic job with Ryzen. 
I don't know, I have buyers for my i7-5820K and offer for i7-5960X.
I need to add 200 euro of my price. Finaly found guy who sell motherboard and CPU for 500euro. And because only sell combo I find him buyer for mobo and I will use CPU, buyer of his mobo will pay me for i7-5820K.  For him I have motherboard, monoblock, watercooling parts are on the way...
What to do... switch to i7-8086K - Z370, switch to Ryzen 2 or even 1800X, Threadripper 1900X, stay with X99 with i7-5960X overclocked is very fast.
Later maybe increase performance with i7-6950X.
 
Rj how you feel with AMD, I know 2-3 more moderators who switch to AMD. Guy from ASUS ROG Forum I talk completely freeked because everything Intel done with Security and sell X99 for Threadripper, X399 Strix make him problem and than switch to Zenith Extreme with 1920X.
I could find Threadripper 1920X for 600, 1950X for 800... I never want to pay full price to processors, only discounts.
Switch to Ryzen 1800X and Crosshair VI Extreme could cost me maybe 200 euro or even less after I sell my parts.
But I need CPU Block, for every change I need CPU block except if I stay with i7-5960X.
Because of that I almost order Supremacy EVO together with my parts. Later I need to wait him 25-26 days.
Somehow reading about many people who switch to AMD influence and on me. Because even people with big budget switch to AMD.
 
I remember one small period when Intel was recommended to people who want to use computer for serious work and AMD for guys who want to play games and save cost. Now looks like Intel dominate in games with fastest core and AMD finish faster every serious job.
I afraid how computer will behave on 4.0GHz in next years... OK now and I keep 4.2GHz only.. but I could increase 200-300MHz more, AMD not.
For 2-3 years example. Because for my needs I have no reason to change platform on 3 years.
 
Who knows how much will Intel ask for Anniversary processors, 100% not same price as i7-8700K.
