Well pc gaming as a whole is a much more customizable experience overall than console gaming, it has better deals on games, you can use any console controller with a pc if you know how to hook it up (if you don't you can just look up how to do it online), building a pc is much easier than people think it is, just watch some youtube videos and read some guides online, and you can most certainly put a pc together for $300, but it's not gonna be top tier quality of course. Now if you want to build a gaming pc for $300 you CAN achieve the same performance as a console if not better, but that's assuming you already have a mouse and keyboard, a monitor or tv to display the image on, and an OS (operating system) ready to go (usually they cost around $100), so if you've got a key for one or you're willing to pirate windows, yeah you can build a pc for $300. So it's possible, you just have to meet those qualifications beforehand. If so then the build I've posted below is what I'd suggest. This build can play just about any game at 1080p 30fps at max settings or 1080p 60fps at low to medium settings. It's excellent for the price. Not every part is high quality, but it's the best you're gonna get for the price.
