To be honest I'd take the $130 i3-6100 + BCLK overclocking over a $150 8370E every day of the week for gaming. Even cheap AMD builds aren't a good idea unless you're literally so low down on the totem pole you can only afford iGPU. The i3-6100 leaves you an easy upgrade path on a modern board, and it's going to end up being as fast or faster than an overclocked 8370E (when the 6100 is overclocked to a typical 4.4ghz). The stock i3-6100 beats a 8320 @ 4.6 in a lot of games too....
The platform cost of going 8320E is still going to be lower for the AMD system since you can pick up a 970 based board dirt cheap, especially if you have some DDR3 to reuse. Given how many downsides there are to non-K overclocking, I don't think it's a slam dunk if you use the computer for other things that can utilize more cores (and you enjoy having you computer keep your feet warm in the winter).
