Dear Friend:
I too have an amiga with dpaint. I have workbench 3.1 inside an amiga 1200 030/50mhz/18 mb ram. This is good enough for me to get the most out of deluxe paint. I used dpaint to make drawings for my pd amiga game 'wizard of the orb' which is on aminet for free.If my system is good enough for dpaint, I am sure your system (much more powerful than mine) is also. Is only the 3d/animation programs that require lots of horsepower, but believe, dpaint does not need a system as powerful as the ones needed for 3d/raytracing.
Your system is good enough -definitely- to use dpaint, etc.
Cheers!!!
