Yeah which is why I had the Vega in what the mac seems to be recognizing as Slot 1, but in "sys info" it's showing it in Slot-2 now, which I would have thought not what it wanted. It wants the 5700 in Slot-1??! But yeah, the Vega is now in the physical top slot instead of the 5700. So you're bang on. Thanks for this insight! Makes more sense, and yes I could have fiddled with the SSDT.
What I do find weird is that all has been working fine for quite a while now, years in fact, since whenever I bought the 5700 to help with Davinci resolve rendering speeds. It was only since updating Catalina with the latest security update did it break everything. Would never have thought the security update would have changed anything that would have required a new SSDT. Additionally, my original Clover SSDT was customized for this machine, and what I'm using now in OpenCore is far more generic as I didn't alter anything at all (just downloaded someone else's that seems to have everything functional because my build is almost identical, just to try it out and play around). But all seems very stable now.
SO there you go!
Congrats on moving to OpenCore! Make sure you follow this to wipe out Clover leftovers.

Depending on how old the EFI you're using, you may need to adjust some things in order for Big Sur support. It also depends on which BIOS version you're on with 3201 and newer seem to be better since ASUS broke the MSR lock functionality in between. Also your previous Clover SSDT may need to be adjusted for OpenCore so that could've been an issue as well.
