A3000 is your best bet as it looks like you will be wanting a graphics
card as a 64 colour dsplay is pretty crappy for mpegs, jpegs, web,
etc.
I run a (fast) high colour 1152x864 dsplay, can't do that on a 600
;-).
The 040 is a heck of a lot faster than the 030 as well! At 40MHz the
040 makes any 030 seem sluggish.
16Mb? Most cards can take 128Mb, mine can. :-)
060 at 66MHz with 128Mb ram is really nice :-)
BTW you can plug in any svga monitor and it will work with all native
modes including games on the 3000! (While you save up for a nice
graphics card to go with it ;-) )
