Need Help with Cortex Configuration

IM pretty new so forgive my stupidity. Im doing really well mining ETH on my first rig and Now i want to take a shot at cortex. Im mining almost all Nvidia 1080Ti because of the pill on ETH. Im really looking for any good advice on which pool does really well on performance and which miner works well with those pools. OC settings are much appreciated but i realize each card seems to need to be tuned. Yes, i would rather have 100 3090s like some people but right now i have 8 1080Ti and Im growing. Im just trying to learn each day a little bit more so i can become more knowledgeable and efficient in my operation.

man I could not mine Cortex till date. Not sure how to.
