All console game are over 30fps for sure. It depends on your resolution. For example;
Battlefield on the Xbox One at 720p does 60fps, whereas Battlefield on the PS4 at 900p also does 60fps.

By online reviews and most console player personal reviews I've noticed that people think the PS4 has better graphics, and I too believe that!
Computers however, is another matter. PC's can go from 10fps to like 1000's+ fps depending on your hardware. The more and better hardware you choose to use, the more money it's going to cost. If moneys not an option, create an extreme gaming rig, with water cooling, loads of storage, the latest graphics cards in an SLI config or whatever because you will, without a doubt, triple (maybe even more) console fps.
You can get a good gaming pc with steady and smooth fps for a really good price if you budget well, maybe for roughly around 600 pounds if you buy all the components and build it yourself. It's not very hard to do if you research about it first, and if you're not adding a custom water cooling loop
😉 As you can see, it's a big difference from the 250/300 pound price tag of a console!
