I'd like to upgrade the 3D graphics on an old PC but would like to keep the video tuner/capture capabilities of its current ATI All-In-Wonder Pro card in the AGP slot. Someone suggested that I could install a VisionTek Xtasy G4 MX420 in one PCI slot (to use as my graphics card) and just retain the ATI tuner/capture software for the AIWPro. Has anyone done this and can summarize the procedure?
