That was so helpful! Thanks!
I would recommend that you do some research before pulling the trigger. By no means am I suggesting "you should listen to me", just look at the testing and decide for yaself. If you check the reviews, Ryzen falls significantly behind cheaper Intel solutions ... anandtech had the 7600k ahead by 21% over Ryzen ... Techpowerup had the difference at 15% taking the GFX cards out of the equation. You also get stuck with substandard audio and LAN solutions, no 2nd monitor using IGP option and other differences.
1. With 8th generation coming out in a week, curious as to the choice of of 6th generation parts.
While Ryzen does many things well, eve better than Intel in certain scenarios, Gaming is certainly not one of them. So I would have to steer you to current generation Intel ... the 7400 outperforms the 1600

"
Gaming frame rates lower than competing Intel chips
Higher power draw than Intel CPUs
Memory frequency options and memory compatibility limited
Setup complicated (memory, HPET, CCX, SMT, and power profile)
Boost frequency significantly lower than on Ryzen 5 1600X
Requires optimized apps of which there are not many
Lacks integrated graphics"
2. Your 1st two items last generation MoBo and RAM are costing you $336.45 Current generation substitutes cost $311.87, putting $25 back in your pocket for better stuff

3. The cooler you have chosen is a good cooler for the money, but for just $12 more, you can reduce CPU temps by > 10C and get a cooler that matches / exceed the $90 performance leaders from Noctua and Cryorig. So far you still $13 richer and you just vastly increased OC ability on an already better build.
4. Your 2 x 8GB 2133 RAM is costing you $170, lets vastly increase the speed to 3000 and save $35 ... now ya have $43 more to spend and again increased performance

5. Your storage is a bit slow.... an SSD is nice but it doesn't do squat for your gaming library unless you have budget for 500 GB - 1 TB SSDs. What we can do however is increase gaming speeds by 50+% by turning that HD into an SSHD as you can see in the link below

An SSD is nice and i'd recommend one if budget allows..... but perhaps this will have to wait for a later upgrade. Boot times will suffer a bit ... SSD does 15.6 seconds / SSHD does 16.5 seconds
The switch to an SSD will cost ya $33 ... so now ya down to $10 extra in ya pocket but storage related gaming performance just went up 50%

6. Switching to the MSI card with the exact same performance specs (1.56GHz), will save ya $10

7. PSU ... PSU is oversized, this one is excellent and rediculously priced ... that frees up $80

In the end... you have:
... moved to current generation with better performance
... greatly expanded your overclocking ability
... storage related gaming performance went up > 50%
... increased RAM speed by almost 50%
... ya have $100 left over which will pay for a top end 250 GB SSD
