Barney,
you likely don't need it unless you do:
- a lot of multitasking between graphics memory hungry applications (graphics memory is not the same as the other memory).
- some video editing on video toaster.
A better investment for A2000 is (in no particular order, although cpu is quite critical):
- faster CPU/accelerator card
- graphics card
- flicker fixer (to connect to vga)
- network card.
