PC always has more power.
Always (If we're talking gaming PCs that are worth their salt).
You must never doubt whether consoles are more powerful.
By default they can't be, as they're very dependent on reaching large amounts of people.
And how do you do that? Well one sure fire way not to do it, is by being very expensive.
Thus you need cheap hardware; but hardware which is still "ok" by most peoples accounts.
That naturally leads you away from very high-end components. Even if you do put high-end
components in a console though, consoles don't change very much over time. This means they're
quickly outdated. With a PC, you can upgrade your hardware as you see fit. So PC is by extension
always the most powerful for gaming and the most flexible. Side note: You wouldn't get an i7 for a gaming
PC unless you're either:
B) The type that has lots of cash to burn.
C) Trying to squeeze out every last bit of performance.
