I would avoid proprietary drivers if at all possible.  

I use an MGA 550 dual head card with X.org (XFree86 before that) free
drivers.  Everything mostly works fine.  I have to disable "Composite"
option on the latest X.org but only because it uses more CPU than I
think it is worth.  DRI and GLX work, but I haven't done tests to know
how fast it is.

You can also use multiple single head cards instead of the more
expensive cards with multiple spigots.
