Your statements about overclocking don't change the fact that buying the i7 over the i5 is 50-75% more expensive and only 5-15% faster, depending on whether you get the 2600K or 2700K. It's still a personal judgement call: do you want to spend that extra money for the small amount of improvement it buys?
There are other areas in a build that can benefit from extra investment, too, like using a SSD for a boot drive, RAID, or a motherboard that supports tri-SLI and a 3rd gfx card.
If you have enough money to maximize performance in every area of a build and you're still asking this kind of question, give us a break and stop trolling.
i love you... hahaha
