Sony's PlayStation 4 may be outselling the competition this console generation, but that doesn't mean everybody has one. Even some PS4 owners might be thinking about upgrading to a PS4 Pro. But whoever you are and whatever your situation is, if you're thinking about buying a PS4, we're here to help. We've put together information about whether to buy a PS4 Slim or PS4 Pro, where to find the best games on the platform, and how to determine what services to subscribe to. Here's your complete PS4 buying guide.

If you're in the market for a PS4, the first decision you need to make is whether you should get a PS4 Slim or the more powerful (and more expensive) PS4 Pro. To make that decision, you mainly need to think about your TV. If you have a 4K television or you're planning to upgrade soon, it's almost certainly worth the additional cost to get the Pro. It will make most games look or play better on your newer television.
