If you ask for a PCI graphic card on the Vampire, then you didn't get the purpose of the project. T SAGA is planar oriented, and Pamela extend the possibilites of Paula letting the way to adress her unchanged.
That would be entirely true (no need for PCI gfx) once SAGA starts supporting Warp3D. I agree RTG on SAGA gives most of what is needed - high-res 24-bit outpout via HDMI, but yet it is 2D only. W3D is not just the thing of few OS3 w3d apps (thus completing the 68k compatibility) its in fact basic OpenGL subset that would be needed for advanced ports.
We ll see what "expansion ports" on V4 models will be used for.,
