Okay so I built this computer and currently I have the i5-2500K Processor and I was looking at the i7 processor and I don't really see a difference in speed so how is the i7 more better?

this is the only i7 processor that fits my motherboard, and I'm currently happy with the i5 which idk why it says it jumps up to 3.7GHz on turbo boost when I've seen it go up to 4.2GHz!

so please, as much detail as possible! act as if you were trying to convince me to by the i7 over the i5 thanks! ^.^
