New to building game pc

[aguy1222]

Im completely new to building a gaming/ entertainment pc and I need help on the build. I been watching some youtube videos on gaming pc builds but im not sure if they are right for me. I will be using the pc to play games like battlefield 4 but I will also be playing my wii, ps2 emulators. I will be hooking it up to my flat screen tv to watch hd blu ray movies. here are some videos I been watching. Budget is $600
