Hi Jacob- Sorry for the dealy in responding. > Hey! In regards to the memory on the video card, will 512MB of video memory > be good combined with 2G of system memory?

I'm not really sure, but generally more is better. ;-) > In regards to the graphics driver; I will very soon be running the IDV under > the Fedora Core 9 Operating System.

I am somewhat confused when it comes to what graphics driver will > be good for running this video card for the IDV under Fedora Core 9 Linux. It's confusing to me as well. NVidia usually has Linux drivers. I would use what's on their site. Don > ---- Unidata IDV Support <address@hidden> wrote: > > Hi Jacob- > > > > > Thanks for your support.
