With the Xbox One at a huge discount ($350), it is a very good contender when it comes to gaming systems. However, gaming PC's are almost always the way to go. Thing is, I only have about $400 to spend, and I won't be getting any more for a while. I know that it is easy to build PC's with a limited budget, but I also need an OS, which would hit the system hard. What do you all think? Would I be able to build a *decent* gaming PC for only $300? Keep in mind that I don't care about running games at ultra 1080p. Low and medium settings are fine for me as long as the frame rate is above 45fps.
