That's awfully much, if those are "reasonbly sized" display modes (by
today's standards) we're talking about here. 200 fps at 1 megapixel
in truecolor is 600 MByte/s --- not counting the second display, or
anything the CPU might have to do besides just pumping pixels. The
AGP interface and your card may be able to handle that load, but your
RAM quite probably won't.
Anyway: what could possibly be the use of driving that screen at 200
fps? Even if you need a factor of 2 to support some 3D shutter
glasses, I'm quite sure that going anywhere beyond 80 Hz (160 Hz with
shutters) is just a waste of effort.

As a matter of fact, I *don't* see why going to DOS would necessarily
help you here. For a start, you're likely to run into rather heavy
problems supporting two screens, let alone two separate graphics
cards, without any help from a driver layer more advanced than plain
old VBE, I think. I don't think VBE ever even remotely supported more
than one display in parallel.
