Pretty much, as an 8350 running 5 ghz
I've been able to push my 8350 to 5.5 ghz @ 1.72 volts ( 1.65 at load), stable enough to run 8 threaded winprime using that motherboard. ( cold ambients with an h-100)
I like it better than my CHV-Z's - no messing around with LLC levels, max thermals etc. just dial up a voltage to the cpu and let her fly.
No throttling, no black screen caused by a safety setting losing it's nerve and shutting the rig down.
The downside to the gd-80 is, all the responsibility for making sure you aren't pushing too hard comes back to you. If you are wreckless, it will probably fry something.
People that don't understand v-droop and how to correct for it shouldn't own this board - simple as that.
People that don't like to use software to overclock , shouldn't own this board. After owning Asrock and ASUS boards and trying to use their software to overclock , I can understand why they don't like it. Some of it is just awful ( AI suite, I'm lookin at you). However , the MSI Control center software works very well.
I really don't know how it would get along with the 9590, but in my case I love the way it handles the 8350 @ 5 ghz
OT how far have you gotten your 965 on that NF980? Good old boards I had 5 of them at one time
