Better yet, save up your money for a machine with an ultra-fast hard
disk and DMA on the SCSI bus.

For most people using current applications, and more than 2 megs of
RAM, it isn't likely that virtual memory will mean that much, unless
of course they like running a dozen open applications in MultiFinder.
In other words, for most word processing, database, telecom, etc.,
most of the application heap will be run in RAM rather than from
a virtual memory space on disk.  Of course, for humongous spreadsheets,
complex Mathematica operations, and 24-bit color scans, virtual memory
will be a boon.

All good things come to those who wait...
