Regarding Spectrum video card. I also happen to run an A3000; 68030-25mhz. The machine is now a A3640 68040-25mhz. Ram is standard 2/16MB and I use 40.68 Kickstart ROMS (aka 3.1).
I have the 2MB GVP Spectrum video card. Works like a champ. You will not be disappointed. On the software side of the equation I have used both original GVP stuff but did end up switching to Cybergraphx 4.
Go for it with the Spectrum I say. They are fairly inexpensive used and I even hear they are available new again from GVP-m (I haven't confirmed this however).
