I had just about the same setup you are proposing, a 4000T from Escom era made by that company in Florida whose name suddenly escapes me, with OS 3.9, Cstorm MK III PPC, Picasso IV running P96 and I transitioned to Cybergraphics and CyberVision. First of all find a CyberVision card was very difficult and the instalation in the 4000T case is a bit tricky. If Villagetronic had gotten the Voodoo module out for the PIV I would probably still be using it, but I did go to the CVision and found it to be a good upgrade though you MUST get the newest Cybergraphics update to use it with OS 3.9 or you will be in a real fix. I did not feel like it was much faster but it did support the higher resolustion and use with a 19" monitor better and for the most part I am glad I did it though I still have a HUGE respect for the PIV card. Another factor in my decision was that the Concierto card did not work under OS 3.9 and the PIV has a pretty large footprint in the Zorro Config space. With the PIV in, some of my other Zorro cards had to go in a certain order or they would not work, the CVision alleviated this somewhat though my Power Flyer Gold IDE card was still a bit tempermental especially with my IO Blix with an Ethernet add on. Ok, the point being without the Picasso it seemd to free up some config space. Good luck with whatever decision you make.
:-D
