Since you'll be doing a lot of computation, a good math coprocessor is a must.
The 387 built into the 486 is significantly faster than the 387-33. I'm not
sure how much faster the Weitek is.

Doing such work under DOS in 16bit is a waste of CPU power. You should really
think of going to 32bit programming. A DOS extender and a good C compiler is
a must. 

Since you'd like to use X Windows and 32bit programming, why not look into
Unix? A good Unix for the PC (such as ESIX) can be had for around $550. If
you use GNU cc you will get decent 32bit performance (a lot faster than you
can get under DOS). Also, there is a lot of PD image processing software
under Unix and X.
