I keep reading there is only a slight advantage to 3930k and for the extra money it cost it isnt worth it. I use my computer for Everything with the majority of it games and web. I didnt know if i made the right choice
Very few games make significant use of more than two cores and web browsing was already a largely trivial task several years ago so for your two primary uses, the i7-3930X is completely overkill. An i5-3570k would have been just about as fast in most cases.
