Actually, 16MB seems to work pretty well on vanilla NT.  Of course,
our dual-processor 90MHz Pentium (Pent-house) system w/32MB running Daytona
does tend to make a 66MHz 486 w/16MB look a little slow. :-)

I agree.  But two things you might want to keep in mind:

  1) Windows95 should be able to support gnat with 8MB.  If you are
     planning for a buy in early part of next year, this is a consideration.

  2) Memory prices seem to have stabilized, but there is a transition
     from 9-bit simms to 18-bit  (72-pin) simms underway.  If you sink
     a lot of money into 9-bit simms for a 486, you may not be able to 
     "take it with you" when you upgrade to a new 586 motherboard.
