Need help/confirmation with my proposed build

Hi all, I've been a console gamer and want to take the plunge into the amazing world of PC gaming! The games I'm looking to play are CS:GO, Rocket League, Squad, Day Z, and other mil-sim type FPS games. My buddy posted on this subreddit a a couple months ago and received a PC part picker list from someone here (Thank you!). With this post, I'd like to confirm the list and see if there are any potential upgrades, gaps, or suggestions you guys have before I buy - https://pcpartpicker.com/list/LbsFv3

Initially the build had an ASUS TUF 4070 ti 12gb, which I have since swapped for an AMD 6950 XT reference card. My motivation here was the $400 discount on the card (https://shop-us-en.amd.com/amd-radeon-rx-6950-xt-graphics/). Is this too good to be true? Should I go with this or something else? I'm open to suggestions and appreciate any advice with the build this since I am a n00b. My budget hopes to stay under $2000, but will spend a little extra if it's worth it :)

Also I noticed the build does not have a wifi card/adapter. Is this something I will need to purchase? I do have access to a Microcenter. Thanks again for the help!
