[SOLVED] Is this Built good?

Solution
Ryzen 3600 outperforms the 2700x in gaming.
The whole build you listed was very expensive. I also agree that the 1070 Ti is extremely expensive and you should go with a current gen graphics card.
In addition to this, the SSD is SATA, not NVMe, meaning it is a lot slower but at the same price. Lastly, the PSU is overkill and you could safely go with a lower wattage.
Here's my opinion:

Depends on what you're using it for, generally yes. However you picked a 2nd gen ryzen 7 chip, the 3rd gen ryzen 5 and 7 have better single core speeds thus making them generally better for gaming. In the majority of games the ryzen 5 3600 will outperform a Ryzen 7 2700x.
