Do note that you can get both of these systems with a GeForce RTX 3080 Ti GPU. It doesn't show on the spec sheet or the online system configurator, but if you contact a sales rep, they'll be able to offer that as an option.
I'm on my second sales rep now, he's looking.
I did find the 3080 available as a choice on Dell's Australian website.
