[Linux-PowerEdge] Video cards for R610/R710

My goal is to get a dual head setup, using middle to low end Nvidia 
cards.  Just a reasonably responsive desktop interface.  Both the R610 
and R710 are currently running on Scientific Linux 7.x.  The nouveau 
driver is getting better and the nvidia drivers are usually pretty 
stable. Haven't really decided which way I'll go on that, probably have 
to test them both and see which one works better.

Finding a setup that would get me to the target and still let me get 
into BIOS and use the iDrac over the network would be ideal. If I have 
to adjust and fiddle around with things during the infrequent trips into 
BIOS I can deal with that. Neither system is a production system, just 
experimenting and some testing happening with these two boxes.
