I love AMD but you should go with Intel at that price. That being said, I wouldn't recommend either of these CPUs for gaming. Buy yourself a FX-8350 and spend the extra $100+ on a better GPU. If you plan to overclock you could easily reach performance of the FX-9xxx.
In either case neither CPU is worth it. Buy a much better GPU instead of a CPU that would increase your game performance negligibly and your high performance compute performance by only 10-15%. I highly recommend the FX-8350, but the i5-3570 is a decent option too if you want Intel.
While usually the 8350 is able to keep up just fine;
there are times where it can't.
There are some games the 8350 just can't keep up on. They seem to be mostly RPGs type games but the fact is it is slower in some.
It's odd that you are getting to OCing chips and don't plan on OCing. Not sure what the point is then. I still think the 3570/4670K is the best value overall. If not, I'd get the cheaper of the 4770 or 8350. That's probably the 8350 seeing as it's priced against the 3570 usually.
Its priced $30 cheaper than the i5-4670k. New games are being optimized for more cores and the new consoles will only further that. That doesn't mean the Intel is bad, its very good, but the AMD wins the value proposition and also the future proof proposition.
