Have you considered some of the other "workstation" class cards from
3dLabs or Appian. 
They need Accelerated-X from xi graphics (www.xig.com) and not standard xorg 
or X86free. But what I understand from their website, xi's X implementation 
is also very good for ATI and Matrox cards. Does anybody have any experience 
with that? (they claim performance massive performance gains, even beating 
ATI's binary drivers for windows and linux in benchmarks)

I have no experience with this stuff,  Nvidia card. But I thought I should 
mention that there are alternatives to Nvidia chips.
