Poor Q800, will go from a top end 68k to a low end PPC.

Built in video is snappy, only bother with a video card if you need high resolution AND color depth. I recommend a Supermac  Thunder 24, they should be cheaper then other cards and have 3MB VRAM for 24 bit color at 1024x768.

Look up Orange Micro for Nubus DOS cards (286-486).
