The Intel i5-4460 is better than the FX-8320E overall no doubt about that. However they way It's explained is very stupid, using CPUBoss is no way of explaining it as the comparisons overall are extremely poorly done on CPU AND GPUBoss.
So if you're going to post on Tom's hardware, you really have to explain it yourself on why the i5-4460 is a better choice over the FX-8320 but also explain which compromises you're taking with the i5-4460 inside 500 dollars. Like the horrific choice of case + power supply (Time bomb), also overall heavy comprimise to compensate for the budget.
The FX-8320E is much more ideal in the 500 dollar budget.
For 550 dollars, i5-4460 + GTX 950 is possible with a few changes...
