What's more compelling for you, the PS4 Pro or Slim?
Well, after building a gaming PC just recently, I found out how important it is to Future-Proof (getting a larger power supply, a better GPU card, a case that fits a larger GPU card, more RAM, etc.).
Paying an extra $100 for a more advanced PS4 Pro may be worth it.
The wait and headache to get one?
Maybe not...
