Hi, my name is Ben and I was informed today that a gaming computar is much cheaper to build than to buy. I'm pretty sure I have a monitor (Its a modern TV, if you could clarify that it is that would be great). I wish to play games like the upcoming battlefield 4, games like that. I also want to play minecraft, battlefield3, runescape, total war, and some others. I wish to have medium graphics, a good speed, and some memory for school work too. If you could help me out that would be great! ( sorry for my grammar) Also, my budget is 800-1200 And im sorry I have no idea where to start, this will be my first build.
