@starf81:
The difference in speed between the CyberVision64 and the PicassoIV quite small, but the PicassoIV should be a bit faster. Anyhow, the PicassoIV is usually very hard to get and expensive, while the CyberVision64 can be found often and for reasonable prices. The difference in speed does not justify the price. If you had an AGA Amiga, the PicassoIV flickerfixer is gold worth though, but as you have an A3000 which has builtin flickerfixer, its not really much of a bonus.
If you go for a CyberVision, make sure you get the real CyberVision64 and not the budget 3d version. The 3d version lacks the very essential monitor passthrough/autoswitcher and is not faster, rather slower, despite the flashy "3d" in its name.
Both the Spectrum and Picasso2 also have a monitor passthrough/autoswitcher. Without one of those, you need to have two monitors (one for native chipset and one for rtg) or have a manual external monitor switcher. This if you want to be able to show both native chipset and rtg output without having to disconnect and connect stuff behind the computer each time.
