You're on Tom's Hardware, and by greater extension, the internet. There's a dozen reviews here that provide all the real world information you're looking for. You just have to look for it.
Don't criticize me. You turned a question about why do you need GDDR5 cards for DX9 Games
(To which I answered: Because there are very few DX9-only games now, most games are going to DX11, Nvidia and soon AMD are discontinuing DX9 cards and driver support, so, you need a GDDR5 card if you expect to keep games playable, which is a perfectly worthwhile answer, and unless you're buying a super low end Nvidia, or a 4 year old card, GDDR3 is a waste of money.) into a debate about FX chips, making your question seem more like bait to try and discuss your views than a legitimate question. So in that case, I'm going to leave these here for you, and then be done with this thread and say have a nice day.

4770K handily beats the FX8350 on every benchmark that Anandtech threw at both of those chips.

CPU Boss shows that the 4770K beats the 8350 in single and multithreaded benches.

Tom Hardware's own review, 4770K beats the 8350 in all productivity tasks they bench it against.

Gaming benchmarks. Look what's consistently near the bottom.
To even come close, you have to spend extra on cooling to OC an FX8350 to come close to a 4770K. Some work productivity tasks, yes, the true multiple cores on the FX8350 wins out, such as rendering and compiling, but not by a significantly large margin that the 4770K can't close in the right overclocker's hands.
AMD hasn't updated their performance line in almost two years. Even Mantle isn't breathing fresh life into them because Mantle seems to only be giving large gains to slower CPUs, not the higher end ones (<10% performance increase in FX chips with Mantle+AMD cards).
