This is my very first machine. It has been rock solid, and I've never had any problems with it. It's my daily use machine, so I do everything on it...from gaming, regular web browsing and video editing from time to time. People say that the MSI Z77A-G45 is a crap board, but for me it has been quite the opposite. I've never encountered any problems with it and it's been rock solid ever since I built it.
