I don't have an nvidia card, but my radeon card has vga, digital and 
s-video outputs.  As for needing two vga, my card came with an adapter 
that converts the digital to accept vga, so I don't think that should be 
a big issue.

I've not had any success (with X) doing as you've noted, two monitors to 
two outputs on the same card.  When I boot my machine with two monitors 
connected, both screens show the boot info and mirror the console output.

I know of folks who have had success with this card and other ati cards 
that have dual outputs.  I've been planning on trying a quick SuSE 
install just to test this scenario, but haven't made the time to do so.

Understand, you don't really need to spend a lot of bucks for a dual 
output card, mine as around $100 when I got it, certainly cheaper now. 
It's only got 32mb (only, I remember when that was a lot of system memory.)

3d is not supported  for dual monitors on XFree, although the 
proprietary drivers for nvidia may well support it.  If so, then you're 
likely to want a card with more memory.

You have to get a later version of XFree to get 3d to work with the 
later ati cards at all.
