i3 4130
but before choosing any of these options i strongly recommend you to consider getting an i5 4430
note- if you plan on using multi threaded applications the fx 6300 is just a bit better
BUT games released today like FC4 dont scale to well on 4+ cores. the usage of my 6,7,8 cores hovr around 40% while gaming in really well optimized games like dragon age , metal gear solid V
The upgrade path of intel is a bit better than AMDs
