Hello. I've never built a computer before and i'm looking to build one or buy one that will work for gaming. I'm an avid gamer and would like to be able to play games like WoW, DayZ, or Skyrim on it. I guess the only thing I care about is that it would need at least 8gb of ram and a 2.8g/hz processor or better. I'm also on a budget of about 900$. Do you think you could help me?
