Hi thanks for your answer 
i have been looking on ebay and such ,they are quite expensive around 200 dollars for a merlin graphics card and picasso
Amiga graphics cards are very rare these days. Dont bother with it if you mainly play games and you are satisfied with low color (less than 64) Workbench. On the other hand if you want to do something more serious stuff on Amiga then graphics cards are must. They dont offer only more colours and better resolutions but graphics also is much faster than using native Amiga display modes.
