AMD CPU's aren't even in the same league for gaming in my book at their price point.

That article assumes outdated prices. Phenom IIs don't cost as much at the time of the writing of the article, so the conclusion page can be completely forgotten.
Also again, the i3 is limited in its functionality for a daily PC. I'll assume a Phenom II 965 priced at $120 set to 18.5 multiplier (which is the stock setting of a 980). Completely fair in Queensbury rules, since you cant do that trick with an i3-2120 priced at $130.
Skryim- Identical performance (less than 5 FPS is identical in terms of reality)
Battlefield 3- Identical, they didn't do benchmarks for multiplayer.. The i3 is not up to snuff for multiplayer.
Just Cause 2- Identical
Starcraft II- i3 has an advantage
Dirt 3- Identical
Metro 2033- Identical
Now lets talk about Daily PC use. Multitasking, surfing the web with multiple windows, etc.

Every program that calls more than 2 cores into play, the i3 gets beaten. This will continue to happen as I mentioned, as software technology catches up to hardware and more programs are written to utilize more than 2 cores. To say they aren't in the same league is a silly statement. I suggest you take "your book" back to the editor for a revision, its not-factual.
And its completely ridiculous that people actually go around telling people on these forums that a crappy H61 with an i3 is actually a better choice than a 965 BE. People are spending real money based on our recommendations, check the fanboy stuff at the door and stick to the facts.
