Finding a good CPU

[stealthyexplosion]

I know which GPU is better than a different GPU. Like it's easy to tell that GTX 770 is better than 570 and 750. But I don't know much about CPUs. I really can't tell which CPU is better than a the other CPU. So how do I know that one type of CPU is better than the other?
Like is i7 better than i5 or vice versa?
PS: This question apply to all CPUs of different brands, not just Intel Core.

Intel cpus :
Best
i7 (LGA 2011-v3) - best for heavy productivity/content creation
i7 (LGA 1150) - best for mild content creation and high-end gaming rigs
i5 (LGA 1150) - best for gaming rigs from $750-1500
i3 (LGA 1150) - best for budget gaming rigs (500-750)
Pentium (LGA 1150) -best for super cheap rigs (500-)
Worst

The 'K' in Intel Cpu numbers (eg. i5 4690k) means it can be overclocked.
The i5 4690k represents the model, with the 4xxx series being the most recent

I was wondering more about how I can tell which series of CPUs is better than the other, much like how GTX 700 series of graphics card are stronger than their 600 series counterparts.
How do I tell when we are talking about CPUs (and I'm not asking for one particular CPU)?

I think what you want to find out has a very long and complicated answer.
However, due to the advance in technology, it`s best to go with the last series, because of the upgrade-ability that you have, along with the improvements provided by the newer generations.

Fine.
But can you answer me on this:
How do I figure out that one CPU and one GPU will be a good combination/match? I don't ask for how to figure out if they are compatible with each other. I've heard that it's not a good idea to have a powerful GPU but a weak CPU or vice verca, so to know how to find the right balance would be nice to know.

Well, most of the current generation CPU`s will not bottleneck even the stronger GPU`s available today.
If you try to pair a strong and new GPU with a low-mid tied CPU from 3-4 years ago, it will most likely result in a bottleneck.
If you have some combination in mind, or you have a budget for a CPU + GPU, just let us know, and we can advise you.

However, maybe someone more experienced will provide with an answer to your liking.
