Personally, I would vote for using the '040 (or even the 030).  I use an
Amiga 3000 daily at work and the graphics feel very slow.  All the work we do
is in high resolution, interlaced 16 color mode, though.  The rest of the
comuter is realy fast, but moving winows, drawing lines, an refreshing the
display feels very slow - especially when compared to the speed of the display
of some other nameless computer...

The blitter is great for low res 320x200 screens, but for really high-res
displays, the '030 would be much better.  Besides, I'm not running a ray
tracer in the background all the time - it would be nice to use some of that
idle computing power to speed up the display.
