I'm helping my cousin build a PC. I haven't built a PC since 2014, and haven't kept myself updated on new hardware much. I'll link the build, any suggestions would be great. And also want to make sure this will all be comparable. Budget is $600. This is currently $575 in my Newegg cart. I have 4 different RX 570's to pick from, recommendation on which to buy would be great. Thanks!
