Need help building a pc

So I have a gtx 1070 8gb graphics card. Id like to hear what good motherboards, intel processors, and 16gb ram cards that go well with it. Id like it to be around $600-$700 or less for the three parts to run games like pubg and gta5 with ease.

(sorry if in wrong forum. don't know which one to put this in.)

 

Intel Core i5-8400 Coffee Lake Six-Core 2.8 GHz Desktop Processor - $180

MSI Z370 GAMING PLUS (Socket LGA1151) USB 3.1 Gen 1 Motherboard - $125

CORSAIR - VENGEANCE LPX Series 16GB (2PK 8GB) 2.4GHz DDR4 Desktop Memory - $140

Total - $445 (USD)

 

Don't forget Microsoft Windows 10 Pro (64-Bit) - Windows $145, case $100, power supply $100 +445=$790
