Be aware that if you installed libGL* with WITHOUT_NOUVEAU=YES in make.conf
then Xorg may get a signal 11 if you use the default configuration for
xorg-server when using nvidia-driver.  You may have done this to support
the ATI card, which I did because I was using the integrated ATI graphics
in my motherboard's chipset until recently.

I have the same MSI card as you have ordered and discovered that I had to
turn off the AIGLX option in xorg-server in order to stop the signal 11
from happening.

Of course, an option would be to remove WITHOUT_NOUVEAU=YES from make.conf
and reinstall libGL*, but I haven't tried that yet.

I'm now successfully using the card with nvidia-driver and things like
VDPAU appear to be working.  No more signal 11.

Ah yes, I also removed dri, drm and radeondrm from my kernel config.
