The FX-8310 from Tiger Direct for $115 is about the most competitive alternative to i3/i5 haswell options. It's a lot of CPU for the money if you can take advantage of it, up to ~50% faster than the i3 in highly parallel workloads (and about on par with an i5 in parallel workloads when compared at stock clocks). On the other hand, the i3/i5 are up to ~50% faster than the FX-8310 in poorly threaded workloads. For gaming, the i3 is faster in more games than the FX-8310, but the 8310 is an interesting alternative, especially for someone who appreciates going the road less traveled on purpose, and is after a sense of novelty or uniqueness more so than just going with the most popular solution.
The 8310 doesn't come with an HSF, so that needs to be considered... I think the smart implementation is to go ahead and buy a nice $30-50 HSF for it, place it on a motherboard with 6+2 or 8+2 phase VRMs (there are a few to choose from around and under $100), in a case with decent airflow, and power it with a nice PSU, all to support some overclocking. By the time this is all said and done, the price to implement will be competing with an i5-4440, and the performance will trade blows with the i5 depending on workload, with the i5 being better in most games, but the 8310 at ~4.5ghz being up to ~40% faster in heavily threaded workloads.
