Overall:
Was looking for a CPU that could perform well today and be future proofed for the next few years. Kabylake 4 core was a bit underwhelming, and the X99 intel chips were overpriced. Ryzen offered great performance / cores per dollar, at the expense of some early adopter issues.

Pros:
1) 8 cores for much less than the equivalent Intel CPU!

Cons:
1) Overclocking on the 1800X should be far better than the 1700X and 1700 but isn't. Also overclocking maxes out with the CPU running at ~55'C, well within any thermal limit.
2) The 20'C offset on CPU temperatures is annoying when designing a quiet system (PWM uses the CPU temperature as a control point, and the PWM % maxes out at CPU of 80'C, which is only 60'C for Ryzen).
3) Overall early adopter teething issues / AMD rushing the product out

Not yet fully optimized for gaming as many know, but this will improve in time as developers and manufacturers have more time with the architecture. It will serve my needs for quite a while though.

Great cpu so far

I cannot recommend this enough.. Even without overclocking, the1800x was well over 2x faster than my 5930k in a volumetric rendering test.. It is just incredible!!!

Great CPU does 4.0ghz on stock voltage almost twice the cinebench score than my previous CPU (6700k) with no appreciable difference in gaming performance for what I play.

I was skeptical about going for the most expensive Ryzen 7 chip, but I figured why not, if you build it, they will come. This processor is fast! My previous build was an A8 6600k, going from that to this, is a huge step. The speed is amazing, I can do everything I need at once and not a single issue with speed comes up. Paired with an AIO cooler, it never gets that hot. At peak with a load I hit about 60 degrees max.

Super fast and I have no complaints.

Rock solid for its price and performance. I read that it can be difficult getting it about 4ghz, didn't have a problem with the Asus software getting it to 4.1ghz and allowing me to bench away.

Intel hasn't made a processor worth upgrading to in 3 years and their next 15% improved 4 core chip won't be something I will invest in either. I use Xeon based blade servers at my job and it involves compile operating systems a lot and when I wanted to learn anything at home my i7 4790k would take forever to compile. The 1800x has cut down the time by almost half! All the Intel mainstream processors like the 7700k get manhandled by the 1800x.

For gaming my performance improved since I always play with 10 chrome tabs, Twitch, Spotify and a couple other things running with my game, also I get much better lows since the cpu isn't pegged at 100% which forced the scheduler to juggle more than it can handle.

So good and so bloody fast. Worth every single penny and once tuned correctly with the rest of components, can be just as good as an 7700k in gaming and an 6900K in rendering. Now I'm just waiting for Vega.
