Will i see any performance gain?

Solution
Presuming you are asking about performance gains.

I suggest you do a bit of testing to find out.
Here is one way:
------------------------------------------------------------
To help clarify your CPU/GPU options, run these two tests:

a) Run YOUR games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This...

It's a steep investment for, in most cases, minimal gains.
I think the GTX 1080 would provide considerably more consistent frames.
But, performance wise, it's a coin flip.
Would I do it with that configuration? No.

My opinion is that no matter, whether it's your current cards or the GTX 1080, you will be bottle-necked by your CPU's single core performance.

Will you see a gain? That depends on how GPU intensive the game is and how it handles SLI.

I think you would see more gains making the jump to i7.

This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.

You should also experiment with removing one core. You can do this in the windows msconfig boot advanced options option. You will need to reboot for the change to take effect. Set the number of processors to less than you have.
This will tell you how sensitive your games are to the benefits of many cores.

If your FPS drops significantly, it is an indicator that your cpu is the limiting factor, and a cpu upgrade is in order.

It is possible that both tests are positive, indicating that you have a well balanced system, and both cpu and gpu need to be upgraded to get better gaming FPS.
-------------------------------------------------------------

If your games are sims, strategy and mmo types, I would guess the cpu is your limiter.
Such games are single threaded and cpu limited.
Your fx-9590 has a single thread passmark rating of 1720.
By comparison, a i5-6600K is 2166 at stock, and most can get a 30% overclock.

If your games are shooters, I might guess you are graphics limited.
You get diminishing returns from the third card, and some games do not play well with dual gpu, let alone 3.
If that is the case, definitely go to GTX1080. Likely one will do the job at anything less than a 4k resolution.
