the reason why it is true is because of the fact that no game uses more than 4 cores, hence why i made the statement "for gaming." The 8150 has a base clock of 3.6 and the 4170 has a clock with 4.2. If both are overclocked, the one with the higher clock assuming both are made with the same architecture will work better in gaming. the only advantage the 8150 will give mostly is through programs that can utilize more than 4 cores, i.e video editing, rendering etc, which was the purpose of why the 8150 was built for.
