Wow, does my head hurt looking at motherboards.
Spoke with Blackmagic tech support and cards that would be required to work with 4K/5K R3D's in HD resolution would be:
Quadro 4000 - Rendering
Quadro 600 - GUI
Red Rocket - Debayering
Decklink Extreme 3D - I/O
I'd like to go with the new Sandybridge-E processor/MB but Blackmagic say thats both of the Nvidia GPU's HAVE to be on x16 slots, then the RR would need a x8 slot. Blackmagic list the P9X79 Pro (http://www.asus.com/Motherboards/Int...specifications) but that board has as shared X16 lane that would become 2x x8 slots when the 2nd Nvidia card was installed with the RR.
The closest I've found is the Maximus IV Extreme Z (http://www.asus.com/Motherboards/Int...specifications) but it is the previous Sandybridge chipset.
BM made it sound like the absolute most important thing in the whole wide world is that both Nvidia cards stay in x16 slots so my question is, would I expect to see a significant performance hit using the Maxiumus board/4-core CPU vs the newer Sandybridge-E P9X79 board/6-core CPU?
Does anyone know of a X79 motherboard with at least two x16 PCIe slots and two x8 slots?
Man, my head hurts just typing that.
Any insight would be greatly appreciated. I'm at the absolute end of my nerd-rope.
