Hello. I am planning to upgrade to one of these CPUs from my old i5-2500. I play games although not very intensive (Terraria, Combat Arms, Minecraft) but mostly I do work on Premier Pro and After Effects CS5. The question is, I was looking up processor rankings when I saw the i7-4820k for 340 USD. At the top of the page it said a newer version has been released. My question is, is a 4 core at 3.7GHz gonna outperform a 6 core at 3GHz? Would it differ for gaming and video editing?
