Did Amiga Technologies change anything with the card vs the older Commodore ones? Are they typically interchangeable with the older mobos? I'll keep it in mind if I get tempted. 
Yes, for one thing (most importantly) they didnt reverse the polarity of the capacitors like Commodore did. Also, its the good 3.1 revision of the board. And, it has a super cool flat heatsink making it fit better in the amigas and makes it especially good for A3000D
