Thanks for the responses.
It is a typo on the card, I plan on going with the 2080. I figured SLI would not be worth the effort since I will only be using the center widescreen for gaming. However, I was under the belief I would still need two gpus for the 6 monitors since I will need 6 total displayport connections. If not using SLI, would there any problem using a cheaper graphics card for the second card? In the past I used a different card in the second slot, but it was for physx only so it wasn't an issue.
Thank you for the input on ram speed, I will adjust accordingly. I still need 32 gb of ram as the trading software is very ram intensive.
