Ivy Bridge: i7 or i5 ???

I've never had Intel before so, how do I determine if I need an Ivy Bridge i7 3770 or if an IB i5 3570 will due just fine?

I have no intention of overclocking because;

1. I'm no gamer (occasional online stuff)
2. I want my system to have a very long lifespan.

Is there a noticeable difference between the i7 3770 and the i5 3570? Is it worth the extra $100?

The only differences I see between the i7 and i5 are:

- $100

- i7 has 4 cores/8 threads while the i5 has 4/4.

How much of a difference will this make and where?

- i7 has HD4000 graphics while i5 has HD2500. I'd prefer the 4k graphics for obvious reasons.

According to this review the i5 3570k was a larger improvement over the Sandy i5 2500k (8%). While the i7 3770k is only a 5% improvement over the Sandy i7 2700:

* However, the Ivy Bridge CPU's consume about 20% less power:

"There were rumors that Intel increased the TDP of the senior 22nm CPUs to 95 watts although had planned to set it at 77 watts. Intel representatives told us that it was just a rumor, though. The actual TDP of the new CPUs, including the Core i7-3770K, is indeed limited to 77 watts but 95 watts is written on their packaging in order to maintain the standard scale of 35/65/95 watts that many Intel partners have got used to. Thus, the Ivy Bridge series can be expected to consume about 20% less power compared to the 95-watt CPUs with the previous microarchitecture."
