If I am not mistaken I am pretty sure there is a guide or list of supported/compatible graphics cards for OS X and what versions of OS X. Lets look at it this way, some cards that were working in earlier versions of OS X are no longer working/supported for instance in Big Sur. Apple has dropped support for a few cards on the way as they are no longer fitted in genuine Macs running Big Sur or the up and coming new OS Monterey.And my desktop with GTX 980Ti?
Unfortunately the price of these cards or their counterparts that are fitted in the new M1 Macs are astronomical and prohibitive at the moment. If you're desperate or on a budget an Nvidia 710 I think will work fine in Catalina or the version before that. Getting back to your iMessage woes, I was involved in the 'iMessage Fix' Thread before it was simplified (The Idiot's Guide). There is a bug on some boards I think it's called the SID bug (it's be so long I been over that thread) but it is where a board would not retain certain aspect of it's data and would just produce a series of random zeros when checked with DeBugger. That problem is so old school though I haven't heard of that happening of late.
Maybe if jay monkey sees this post he could maybe point you in the right direction and/or offer a possible fix.
PS - Post the readout from DeBugger so we can have a look and see if anything can be gleaned from it or something you maybe missing.
