I have the XFX dual DVI FX 5700 Ultra card on Windows. I see a lot
of posts regarding dual display woes with a 5700 and Linux, more than any other NVIDIA card in recent times. Perhaps this is because of the popularity of the 5700 and its dual-DVI goodness.
If you get one of these, look for the XFX 5700 Ultra with GDDR3
instead of the XFX with DDRII
. DDRII RAMs run very much hotter than DDR3.
