I was building it based on gaming part.
From techspot
The problem for AMD, which we have seen time and time again, is core efficiency. Having more cores available isn't much use if they are slower. Moreover, just because a game can use four cores (and all the games we tested could) doesn't mean a dual-core will be inferior if two cores are working harder than four.
Most of the games saw the Athlon X4 860K working all four cores at 70% capacity or greater, with a few such as Civilization: Beyond Earth, Thief, Battlefield Hardline and Battlefield 4 reaching 90%. Despite that, in all of those games the Pentium G3258 was as fast or faster than the Athlon X4 860K.
Focusing on the overclocked 4.4GHz results we found that on average the Pentium G3258 was 15% faster than the Athlon X4 860K when paired with the Radeon R9 285 and 14% faster with the GeForce GTX 960.
If we remove Assassin's Creed Unity results, which saw the Athlon X4 860K deliver abnormally low results, the G3258 was still 13% faster with the R9 285 and 9% faster with the GTX 960.
