Do you game at all? Surely you've played games which give no where near the FPS shown on the reviews. That's what I'm saying.
They do not test the CPU bottlenecked areas of games. How am I supposed to show you them from a review site.
Play WoW. Now look at this benchmark:
http://www.anandtech.com/bench/CPU/62
If you've played WoW, you know that you will get 40 or lower FPS in raids on the same CPU's that get over 100 in that benchmark. You don't see it, because they go to an out of the way place, to make sure there are no people involved, to avoid inconsistent results from other players.
Now take Arma 3:

That's one that flat gets low FPS even in single player, but in multiplayer, the FPS are 20 lower than that.
Neverwinter:

Like most benchmarks, they avoid players, and don't show raids or events with lots of players around, and even then, CPU's bottleneck.
That's the best I can do atm. The problem is that you can't find a reputable review that shows online results, or goes to CPU bound locations of games. They do most their reviews to test GPU's, and stick with the same benchmarks with CPU's. Because they use them mostly for GPU benchmarks, these benchmarks show very high FPS when testing CPU's. Real world gaming is quite different.
Edit: Here is another that shows a clear bottleneck on GTA V. It's clearly done in a different place than those others being shown around here:
