Hello,
I need to build a graphics Workstation with one professional graphics controller (PCIe 16x) and 2 LSI MegaRAID 8i controllers (both at PCIe 8x) installed.

(edit-insert)

Sorry, I neglected to add that this Graphics-Workstation (Windows7-64) is used for Video editing.
This means: large files (sometimes several) are read from any of the 2 LSI MeagRAIDs while (often at the same time) Video-sequences are cut, pasted, rendered etc.

Chipsets are X79, Z87. Any other suggestion?
Specific suggestions for Mobo ?

I find it hard to find a suitable motherboard that supports the PCIe (gen3) bandwidth without limitations.

Which Motherboard(s) would conform (or best meet) to the setup described?

Your advice is highly appreciated.
Thanks
