I have an nVidia 510 in a Dell Optiplex 9010, small form factor computer
using CentOS 6.4.  It works well with the standard nouveau driver.

I used to use Matrox M9140 cards, but that requires the Matrox proprietary
driver which, at the time (April 2013), had not been updated to install
on CentOS 6.4.  Perhaps by now it has.

However, I like the NVS 510 and I'll use them in the future.

Is the NVS 450 card one or two GPUs?  If two, you'll have two video cards
and you'll probably have to stitch the monitors together with xinerama.

Matrox M-series M9138 or M9148

As an amateur astronomer, I'm a little envious.  However, I probably
wouldn't do well at 2380 m altitude.
