Post is rather old to be responding to. CPU Boss is a rather useless site to use as a reference. Comparing raw numbers and values only gets you so far. And looking at CPU only metrics is not what people are after for gaming. On CPU bound games the single core performance of an Intel chip really does blow the 6/8 cores of the FX out of the water. Some of the latest games are decently multithreaded, but still the main processes benefit from the single core performance far more.
Now if I wanted to know how quickly a computer can unzip a file or process an image, then certainly the metric from cpubenchmark would be useful.
Process node is a fine comparison, but only really applies to similar architectures. ie Broadwell at 14nm vs Haswell at 22nm.
FX processor technology is about 4 years old now. AMD does have lower power CPUs in the 95W and 65W range, just as Intel has higher power chips up to 150W.
Just not really a good recommendation to go for an AMD setup unless you are budget restricted. Then the overclocking potential comes in handy to get more performance for the dollar.
Kind of an old debate, but there is not much you can justify getting an FX processor for. Another generation from Intel is available, so far only the unlocked chips, but give it a few weeks/months and you will see a locked i5 that should be worth looking into. Another 10% or on top of the i5-4460 just reduces what an few multipliers on an FX chip will get you.
