Save yourself some money AND get a better card than the Quadro 4000. Go with a GTX 470 as a replacement for 1 of your GT120’s. You have the PCIe space and the 2 power connectors as your other GT120 doesn’t require them. It will be cheaper and more powerful (CUDA cores). See Macvids on ebay for them.

I suspect that what you are looking for won’t actually be implemented until the Thunderbolt v2 comes out. Currently the speed of Thunderbolt (10 Gb/s) still can’t match the speed of your PCIe slots. With v2 that would become more of a reality as it will exponentially increase in speed (100 Gb/s).

Great stuff. Very clear.

[Andreas Wideroe] ” From my 1200W power supply. ;-)”
What power supply is this and how are you hooking into your Mac?
Thx.

Here is an interesting solution:

The problem is that there are only 2 connectors in a Mac Pro, which means you have to go with a GT120 (which doesn’t need any connectors) in order to support more than 1 card and therefore the GUI. That’s where cubix can come in handy….

I have the heard that the cuda drivers are now automatically integrated in Lion (OSX 10.7).
There is a listing on ebay somewhere for GTX 470, which explains this in the description….just found it:
“You will need to download the Quadro 4000 drivers from the Nvidia website. You will also need to remove “AppleGraphicsPowerManagement.kext” from your Extensions folder. (S/L/E) You can choose to modify and reinstall this kext or just leave it out of the folder, otherwise it will throttle the card down to low speeds.
With a SPECIAL EFI ROM by renowned Mac Guru, The Rominator with additional help from the Master of Mac Mods, Netkas….
Tested & working in Mac OS X Lion 10.7 GM (11A511) , no need for drivers, now included in OS. Just need to remove the AGPM kext !!!”
Hope that helps…

“Waiting for the Decklink 4K approval…. ”
Thanks for your reply. Not sure what you meant about 4k approval though, could you expand on that?
Thanks,

In that circumstance (TB breakout box) which might be a better card paired with an iMac, a GTX 285 or the newer Quadro 4000? It appears that Davinci indicates Resolve is still optimized for the older GTX285 rather than the newer card. However that card still needs 2 power connections.
