It only takes a CPU more or a little bit less than $100 to run Minecraft at a consistently high framerate, even higher than 60 fps in some cases.
Given that the rest of an average PC shouldn't cost more than approx. $185, you can pay the same price (or even less) of the cost of a console for a PC that can run minecraft WAY better, and definitely at 60 fps. You probably wouldn't even need to include a graphics card for Minecraft, since it's not even that graphically intensive of game. (Probably the only reason why it can manage a consistent framerate on a console)
- $60 motherboard
- $25 4gb ram
- $40 PSU
- $40 tower
- $20 keyboard/mice combo
- $120 CPU
These are just average prices for building a good computer capable of properly running Minecraft without taking a graphics card into account. And obviously, depending on what models you're looking at or what places you are buying from, these prices can vary and become much lower. Assuming your math skills are better than your research skills, you can conclude that this is indeed cheaper than a console. My work here is done, any more questions, feel free to ask. Have a good day.
