How do you guys feel about gigahertz in processors it has really been forgotten about intel and AMD have flagships clocked at around 3.5-4.00 GHz do you think we need to start getting more like 7 andthings considering we're in 2016?

It depends on what you're doing, as having a higher-clocked dual-core processor will perform better at single thread tasks than a lower-clocked quad-core processor will. At the same time, that same lower-clocked quad-core processor will perform much better in multi-thread tasks than that same higher-clocked dual-core processor.

Basically, I feel like it depends really on whether you need more cores for faster multi-thread tasks or whether you need higher clock speeds for faster single-thread tasks. This is also why I like the 2.7 GHz dual-core Core i5 in my MacBook Pro, I do more single-thread tasks than multi-thread tasks, so I can get by having two cores at 2.7 GHz that will clock up to 3.1 GHz when needed.

I use Intel Quad Core i5 3.1Hz on my PC. It's more than enough power for the tasks/games I normally run.

My Macbook Air is 1.6ghz, and that is absolutely fine for what I do (not much, but stuff like music,videos and homework)

The issue is that such a high clock speed requires a very good cooling system, which is impossible to implement in laptops except for a few hardcore ones.
This is also the reason why dual and quad-core processors started to appear.

It doesn't make too much sense talking in clock frequencies anymore. Before, processor competitors were rivaling to reach the highest clock speeds. See the myth on Wikipedia (https://en.wikipedia.org/wiki/Megahertz_myth)
