experiences with dual-dvi on ATI Radeon cards / NV-cards

[Martin Schuhmacher]

Hello,
at the moment I'm using a Matrox G550 on PCIe Card.
Its not that good on 2D. It seems, the closed driver is ugly.

So, a new Card is to come... I have the choice between ATI and
NVidia. At the moment i saw the "ATI Radeon X1650 PRO".
What about the ati driver performance on 2d ?
Since the bad experiences with the matrox, is it known to work
with x.org 7.0 on dual dvi ?

thanks in advance
Martin*
