> What would be the best card options for PCIe and MorphOS?

If best means fastest and you don't want to forgo 3D hardware acceleration, there're 3 options:

- X1900GT with PPC ROM (rare, expensive)
- X19xx flashed with X1900GT PPC ROM (big chance to misbehave or simply fail)
- X19xx with AtomBIOS ROM (no access to OpenFirmware)
