I have a friend who asked me if I could help him with getting a good gaming and recording pc. He needs a new monitor, mouse (for FPS and MMO games), keyboard and Windows 8. He wants to be able to record and play games at 720p at a minimum of 30 FPS. He wants to play games like minecraft, Bioshock Infinite, BF3, etc. His budget is $600 dollars.
Save up, don't buy windows, get your preffered peripherials and fill out the model thread. People will help you more that way.
