Here's a review on the FX 8350 by Techreport. I think their results are more accurate. For example in Crysis 2...
i5 3570K - 88 FPS
i7 3960X - 87 FPS
FX-8350 - 86 FPS
i3-3225 - 82 FPS

Even an i3 will do almost what the much, much, much faster i7 3960X will do at 1080P which just so happens to do just about same thing a FX 8350 does...
I'm sure the guys in the video did their video with good intentions, but yeah... I'd at least like to see someone do the exact same testing they did and come up with the exact/similar results. Otherwise, some of the numbers I don't trust at all.
