Hello Michele,

The ABW mode is sort of a rudimentary built in RIP, only in the sense
that it blends the color inks to emulate BW tones. Real RIPS do that
and much more, giving a huge amount of control beyond what ABW offers.
Whether you want/need that extra control is another matter.
ABW can produce very fine BW prints as is (article #9 at the link
below outlines a very good and simple ABW workflow). But if, for
example, you wanted to eliminate all Y and do the toning with only LC
and LM, then you'd need a RIP to control each ink. Using a RIP
involves a learning curve and more time and effort, so like
everything, there's a trade off.
Nice thing about the K3 printers is you can start with ABW and move
into a RIP later if you feel the need. There's no need to decide
before you buy the printer.

Beyond using a RIP or not, there are advantages to using K3 inks,
especially with the semi-glossy papers. So the 3800 would be a good
investment with or without a RIP.
