Value of RTG Card in a A3000?

[Caius]

I think he's puzzled because your signature implies that you already have an A4000 with a Picasso IV, so it's a little strange that you don't already know how much better most RTG cards are compared to the A3000 native output.

I was just asking a question which I thought was part of the purpose of this site, not asking to have my inadequate post critiqued line by line, sheesh.

I didn't mean this as critisism, nor did I sense anyone else meant it as such. Let me try being more helpful then. I think the best option for your A3000 is to get a graphics card with a passthrough port so you can route the machine's builtin scandoubler/flickerfixer through it and get a one-monitor solution. These cards also have a built-in monitor switcher so that the front most screen is displayed no matter whether this is RTG mode or native mode. The CyberVision 64 is arguably the best choice (I'm sure someone will disagree though), however the Spectrum 28/24 is probably easiest to get a hold on since SoftwareHut seems to be selling these now.
