The reason why you won't be seeing any difference is because the I7 is already extremely powerfull. To persue a different analogy, the i7 is 20 ton loaded truck: If you get hit by that thing speeding at 100 KPH, you are quite dead. If you get hit by it at 120 KPH, you are also quite dead. The difference only matters to a very small amount of people (in this case, the forensics department, in your case, benchmarks, processing software, scientific experiments), but for everyone else (newspaper, friends and family, or in your case, games and word and Windows) there's no noticable difference.
