The key thing I've found that matters (outside of the supported res and
gpu and such) is onboard dedicated video ram. if you get a 128mb or a
256mb card you'll be fine. 64mb is pushing it for dual head and I think
you'll hate the performance.
Another question is are your CRT monitors digital/DVI or VGA? If
they're VGA and you are using the DVI to VGA adapter, then the res isn't
really an issue. 21 inchers at 1600....hmmm you might really want the
256 card. Are those Viewsonics by chance? Just a curious guess.
