What are some good inexpensive specs for running UE4?

Dont get a AMD 6 or 8 Core, they are somewhat slow in games and a waste of money.
For example the elemental demo uses only 3 cores.

Here is a cpu benchmark which includes following games:
Anno2070, Battlefield4, Crysis3, F1 2013, Starcraft2, Skyrim


As you see here an i3 4330 beats every AMD cpu except the 9590.

Intel has a much better architecture, and a much better per core performance,
and they have a lower TDP.
