When paired with mid range GPU like 280, the 860k will give you same results in GPU intensive games like the most expensive i7. Considering how cheap it is, it might be the best option for budget gaming PC.

What a bogus claim, the single thread performance of an i7 (or even i3) is going to beat out the 860k for non-cpu demanding games, thus you will notice the difference in anything that could be classified as "GPU-Intensive; sure something not stressing the system will run close to the same on both systems. Now when you talk about cpu-demanding games, it is not even fair to compare the two.
