X4 860k doesn't have any logical cores, it has 4 physical cores. Per core, Intel is much much better than AMD.
The 6300 however has 6 physical cores and a nice 3.5 clock.
Not sure why you're so dead set on the 860k. It's old and weak. Spend the extra $10~, it would be so worth it.
The FX-6300 is £20 ($31) more expensive, and I thought the whole reason Intel is better per core is hyper threading.
No, the reason Intel is better for gaming is because the individual cores are more effective per clock.
For example, your E2200 @2.20 has a passmark rating of 1196.
By comparison, the G3258 @3.2 has a passmark rating of 3995.
A 45% increase in clock speed results in a 345% increase in performance.
And, that is before overclocking which can be expected to be 4.0-4.2 conservatively.
Most games depend on the performance if the single master core.
The individual cores of the X4-860K are about 40% slower than the G3258.
On the graphics side, the G3258 integrated graphics is about the same capability as your 9400GT.
You will likely want a stronger discrete graphics card, but I would try out integrated graphics first.
You will get a better idea of what you actually need.
My guess is that you would find something like a R7-260 or GTX750 to be sufficient.
