Suitable overclock speed for my GTX 1060

[Sadolm]

So i've been planning to overclock my components of my PC but as a first-timer i've not a single clue on what kind of speeds i can overclock to.
The things i want to overclock are:
CPU: Intel i5 6600k
GPU: Gigabyte GTX 1060 G1 Gaming
Memory?

I've looked on some guides on how to overclock my CPU and i think i'm going to overclock it to 4.2 Ghz at 1.25V
Now for the GPU i have not a single idea since most of the youtube videos dont really cover the specific GPU i have and i've heard stories of GPUs breaking..

What i really want to know is: if i should overclock my GPU at all, if so, to what speed should i clock it to, do i have to increase voltages, do i have to get a better powersupply and what about memory overclock?

I know these are a lot of questions but these forums have worked out for me in the past pretty good so i thought i might give it another shot.

Specs:
PSU: Sharkoon WPM600 Bronze
SSD: Adata Premier Pro SP900 256GB
SATA: Seag 1TB ST1000DM003 7200 SA3
Memory: 16GB 2133-33 Vengeance LPX
CPU: Intel Core i5-6600K
CPU cooler: Noctua NH-D15
GPU: Gigabyte 6Gb 1060 G1-Gaming
Motherboard: Gigabyte GA-Z170-Gaming K3
Case: Sharkoon T28 (red)

NOTE: i am going to replace my PSU with a corsair RM650x since i am worried about the safety of my current one.
Also i'm sorry for any grammar errors.

I have an ASUS 1060 6gb turbo. I use the ASUS GPU tweak 2 OC the card.
I have +232 on core clock and +887 on memory clock.
Power target and voltage upped to the max.

I ran heaven and valley, passed them a couple of times with no artifacts, all just under 70 degrees. Bf1 has 99% GPU usage, never had a crash. I had crashes with Dark souls 3, GTA V, and recently warframe(only happened once). Downclocking the memory solved the crashes in some cases.
