I know flat to nothing about actually building a computer, but it seems simple. I might just pay someone to put it together, but everyone is telling my building my own would be cheaper then buying a pre-built. I have a budget of about 1400 to spend , but I wouldn't wanna spend it all. I want to have a i7 and a 770, MAYBE a 780 if It could get in budget, but I don't know. Any help building this will be very MUCH appreciated. I just don't understand what goes with what on the parts. THANKS IN ADVANCE ! <3
