First Contact wasn't supposed to be complete in terms devices being supported by OS4. It was done to get boards out to people keen to get systems out to people who were prepared to accept that not everything would be working straight away.
This isn't something that was hidden from the customer so why make such a fuss, especially when you aren't a customer.
VERY weird.
However, I doubt OS4 supports dual graphic cards.
In fact, I'd be surprised if it even supported dual monitors on one HD4650.
Hopefully, in the future, onboard hardware drivers will eliminate the need to use so many cards.

tinkering? Hell, I like to completely tear things apart and rebuild them however I want!
OS4 supports multiple video cards. I have a Radeon 9250 and an X1550 in my XE and there is no problem with running different apps on both cards at the same time. You can do same with a classic Amiga under OS3. A card with dual outputs can only currently display the same image
Chris is advising caution because he doesn't want inexperienced users causing warranty issues. Most competent users will just change what they like anyway. Changing the heatsink and fan will void the warranty but I think anything else is just advice.
