Overclock/undervolt 5080 Aorus Extreme WC. NEWB.

Let me preface this with, I have never overclocked before, I’m a complete newb. I have been trying to source material to educate myself on the subject but all the videos on YT I’m seeing are not very beginner friendly or are 2+ years old on previous gen cards. How much of a difference this makes I am unsure. I am very willing to learn myself but I can’t seem to find anything that starts from the ground up, everything I’ve seen assumes you have some experience.

1. Software – more or less all the vids I have watched have used MSI Afterburner. I take it this is a given? I did see in one of Jaytwocents vids that he said he had more options on a gigabyte card using the gigabyte software.

2. Aim – Performance gain that’s stable. I’m not interested in trying to break records, although its been very interesting to watch, If someone is able to say ‘set this to this and that to that and that will give you X% performance increase’ that would be great, please let me know, but id like to have a little understanding of why this works and then in the future can have ago myself.

3. Other factors – I appreciate this is where another rabbit hole begins but what else can/should I do to other parts of my system to try to ensure stability?

My system –
7800x3d
32gb cl30 6000 RAM
MSI Carbon X870E motherboard
Gigabyte 5080 Aorus Extreme WC
ROG strix 1000w PSU.

Thank you in advance for any advice and help given.
