One more question, Todd. Bare Feats did some benchmark tests and got great results using the Nvidea Quadro 4000 as a slave card. They described this setup as using the ATI Radeon card hooked up to display and the Nvidea Quadro 4000 occupying another PCIE slot, not hooked up for display. Just number crunching.

The results were amazing. Are you familiar with this concept and can you refer me to any info that can elaborate on this type of setup? (I have a early 2008 Mac Pro with 8 gigs and a ATI Radeon 3870 card.)
