I know how sockets work on cpus but I plan to upgrade to an i7 6700k which is the LGA 1151, I have the i5 (LGA 1150) would I need a new mobo?

Also whats the cheapest mobo and cooler for that CPU (I7 6700k)

Roughly 10% increase on direct CPU comparisons (i5 to i5, i7 to i7), which is nice but not noticeable to most people. However moving from an i5 to an i7 will have an significance performance difference if the software you're using can take advantage of multi threading. Look in to your music software and see if it takes advantage of multithreading or not.

If you were building from scratch, I'd say go Skylake as the costs are roughly the same as building a new Haswell system. However since you're only wanting to move to an i7, I dont know if playing an extra $200-$300 would be worth it to you. You might be better off putting that money in to a better video card for gaming or increase in Memory and SSD's for the music editing.
You're going to need a new motherboard and new RAM if you make the jump to a 1151 system. Why are you wanting to upgrade? The difference between a Haswell (presumed) and a skylake system are usually not worth the cost unless you have a specific need.

I was told that there was a big difference between skylake and haswell.... Knowing this I will not upgrade... However I mainly use this rig for gaming and music editing? would it make a difference?

1) Even the i5-4460 is a very good CPU and rarely a bottleneck for gaming.

2) i7-6700K as said for multi-threaded can help but for AUDIO it's likely already so fast it wouldn't be worth the cost even if it could use all eight threads of a 4C/8T CPU.

Thus, assuming a 3.9GHz Turbo CPU like the i5-4690 you would probably encode somewhere between 25% and 50% faster (likely closer to 25%). So if it took TEN MINUTES before then it would take maybe SEVEN to EIGHT MINUTES now.

Hard to compare, but as a rough estimate assume 4.4/(your i5)*1.1 for programs that can't use HT and at best probably no more than 1.2X on top of that (on average).

3) You'd need:
a) new CPU (i7-6700K)
b) new motherboard
c) new DDR memory (do NOT use DDR3 memory and a board that supports DDR3 to save money. You can kill the CPU and that's well documented)
d) Windows (new copy)

*So that's maybe $700+ you'd have to spend for minimal to no benefit in most games, and time savings for audio processing that may not matter if already fast enough.

There are much better ways to spend that money:
1) asynchronous monitor (GSYNC for NVidia, Freesynd for AMD GPU)
2) speakers/headphones
3) better GPU like GTX980Ti (or save for Pascal or AMD's solution)
