Mathew Reuther :
Why is the FX-8350 a second tier CPU on the monthly "gaming" hierarchy chart if it outperforms an i5-3550, which is a tier one chip?
Because in the majority of modern games, it does not perform anywhere near a Core i5. It usually performs in the neighborhood of the Core i3.
Watch Dogs is an outlier, and the Crysis II link you provided is obviously bottlenecked by the GPU so we're talking about insignificant differences within the margin of error there. In that same chart, the core i5-2500 beat the 8350 by a couple FPS out of about 120. Its limited by the graphics card.
If Watch Dogs were the only game on earth the recommendations would be different, but we have to generalize.
In the future, if more heavily-threaded games arrive, that might change too.
