Some observations after having a Ryzen build for a bit. The ram issues seem to have been mostly addressed. It's still picky about what ram it likes, but of the choices you have available, all of them seem to work mostly fine now out of the box.
Ryzen seems to be VERY power efficient. My cpu fan rarely spins up, and very rarely leaves the 40-50 degree range. It helps that it's designed on a 14nm process and the processor I have is a 65watt cpu. I have under volted my cpu and actually gained a bit of cpu performance. While saving power. That's just perfect for me. I love power efficient tech, because heat kills. I have 2 fans in my case not including the cpu cooler and graphics card fans, and it runs at great temps.
The power of this chip after what I had before, doesn't seem to be mind blowingly insane, but it's 3x the cpu I had, and nothing gives it trouble. There's not a game I can't play at max settings 1080p at 60fps. Anything higher and you can start to push it on some games though. Which was a bit of a disappointment. I'm sure the higher end cpus address this though easily. And if I chose to overclock, I'm sure I could easily run anything with high settings at higher frame rates.
I've been completely satisfied with this purchase. The 1600 is about all you need at this time for anything you're doing. It's a great chip all around for anything. I personally might have went with the cheapest 8 core chip if I did it over again. But I'm still completely satisfied. I've always been in the price/performance category when buying computer parts, and this doesn't disappoint for the performance and price point it's at. I highly suggest this, or if you have a little cash to spare, the cheapest 8 core version of Ryzen. I also have a Sapphire RX 470 8 gig video card that helps chew through most anything I throw at it. Those two components will future proof you for a couple years at this point. That's about all I can ask for a 4-500 dollar investment. And well worth every penny. The components I bought all feel really well built too and like they'll last for a long time to come. We'll see.
