The i5 4440 is the best option. Frequency means nothing across different architecture.
While AMD offers a great budget orientated processor, the line is sadly a dead end. Intel has the habit of changing sockets but they are able to produce strong processors at a reasonable price. Until about 6 months ago, I've recommended more AMD builds than Intel. But now I feel we've hit a turning point. In terms of system longevity, Intel is the choice.
As for the fanboy-ism. I'm tired of hearing the phrase "Buy an 8-core. Newer games are going to use more threads." People said this before AMD released the 8-core. It's been over 3 years now since AMD released the FX line. I have yet to see an new game that an Intel i5 doesn't match or surpass the an FX 8-core. Games are predominately designed to be Single threaded. There are very few games on the market that actually need more than 4 cores or that are multi-threaded. And even than, the games that do use more than 4 cores (or Intel HT), there is a small performance difference between the 4 core vs 4+ core/HT.
I've said this many times, I'll believe it when I see it. I have yet to see it in over 3 years.
