because i7 2600k has no significant advantage over i5 2500k in gaming... while being $95 expensive than the latter... so why pay more for nothing? i7 2600k is better suited for heavily multi-threaded task and thats outside of gaming scope....
okay thanks! computer technology is incredible, I built something in February for 1k and now a few months later for $500 more u build something 10x better.
