Hi Henry,
That is a theme that I never have touched here. To be honest, I’m quite happy about it, as things change rapidly: Todays hottest can be the latest tomorrow. So a good tip can backfire a lot.
Of course, I would love to “rub the crystal ball” and tell you what a good long time investment would be.
Quite frankly, I really don’t know, and I admire people who give easily advice about that, but after many decades in this business, I do not feel at all comfortable to play games with other people’s money.
Perhaps explore which AMD card would work in your set up, but check with the support first, and again - the ProRender is in [kind of] beta!
All the best
