I am glad that BoingBag 3 has motivated people to use more their Amigas!
All recomendations are good, the choices you make should really depend on your point of view and Amiga usage. It is allways a good policy to try out things out first, and then decide based on results you get.
By the way, you ´ve got a very nice AGA setup!
PS: Has anyone tryed CybergraphX 4.x AGA driver on a 68k? How does it perform?
