Hey, I'm kinda trying to build a custom PC and when I got to the point of CPUs I started wondering why does the i5-3470k cost like 40€ / $55 less than i5-3570k? I know that most gamers use the i5-3570k but at the very moment I'm on a tight budget and I kind-of need to save that money.
Would the 3470k be much worse than 3570k in games like BF4?
