As a fellow Mac lover, I caved in two years ago and got a Windows machine for the 3D stuff. I'd been using Daz on a Mac for years, and resisted switching to Iray for that reason, even though my Macbook had a (low-level) Nvidia card. Everything 3D is soooo much easier on a Windows computer. I still do everything else on the Mac, because I just love the way they work, but my art stuff is better on a Windows machine. Not incrementally better--levels of magnitude better.
And if you're going to invest in that, save yourself annoyance and frustration and just go with Nvidia. AMD makes some great graphics cards for other applications, but so much of what you're probably going to want to do eventually will all work better on an Nvidia card. When I started with Reallusion products, I had no idea I'd eventually want to play with Unreal or the new Omniverse, but now I do, and those only work decently (or at all, depending) with Nvidia. Iray only works decently with Nvidia. And pretty much *everything* will be faster with Nvidia.
I'm writing this on a Mac, because I truly do everything except graphics on the Mac, but anything animation, or 3D, or video editing...that's for the Windows.
Just some friendly advice...

Edited to add:
We're currently in the worst time ever to try to build a PC because of the all-around parts shortage, but especially 30-series Nvidia cards. I know a couple of users recently got awesome sounding Alienware pre-built systems with 3090 cards that make me drool, so you might want to look at those, if you're going for a desktop. If you're looking at a laptop, understand a 3080 card in a laptop (which is what I got and waited 3 months for) is not the same graphics card as a 3080 in a desktop...but compared to my 1070, it's gold. :-) I bought this
https://xoticpc.com/products/asus-rog-scar-17-g733qs-xs98q with upgrades to 64gigs ram, and two 2tb drives. I JUST got it two days ago, so haven't really had time to play yet, but so far, I love it.
