I've been out of the PC hardware loop for a few years now. I only pay attention when it's time for me to upgrade, and since I always go for the best in my own builds it's always been simple. However my sister has asked for help building a PC for my nephew. I'm not sure exactley what games he plays, I know fortnight is one of them, Only info I've gotten from them is hes looking to play 120hz or possibly 240hz 1080p. She told me they would spend about 900usd for PC, and 200-300 for monitor. I started going through PC Part picker and there are so many choices. Since I don't have too much time to research hours and hours of reviews, and videos between now and Christmas (There going to give him money to build it, so I dont need to build it before christmas just a build list for price) Id appreciate any advice or example builds you could share.
