Also, Dave, I meant to add, if I upgrade only to 10, I can keep this Mac 1,1 and upgrade to OS 10.6, I've already added 16GB memory.

If I can find an HD Native card, I'll need to get a new cheesegrater to get all the way up to 12. So, I'd be looking at a 5,1, at least 16GB memory.

I had not realized that an HD Native PCIe card would do what I needed. I kept thinking I would need an HDX capable I/O along the lines of a new model 192.

so, more research is required. Thank you!
