Re: Two 4800s vs Three 4000s?

Sorry to bring up an old thread but what does this mean to most experience users:
Currently the Nvidia Quadro FX 4800 card provides the best performance in a 1 GPU DaVinci Resolve system.
Got that from the Support site.
Reason Im asking is that I have an old 4800 sittin on a new Lion box by itself.
We have a CUBIX with a single 4000 and planning to add another.
Should I turn the 4800 box into a back-up for Resolve.
We have an extra REDRocket we can add to that.
Not sure if the RRC will help with Resolve but it could make a nice temp DIT system.
