kgp,
I've been looking at building something to replace my aging (real) 5,1 and found your excellent build description. I'm placing an order matching what I saw here. Sorry for the deluge of questions, I will post my findings as I go along with the build.
I'm ordering the X99-Deluxe II on the assumption I can bond both ethernet ports as I currently do on my 5,1. Is that a valid assumption? If I cannot bond both ports, there is no reason for the Deluxe II. Better yet would be a 10G Ethernet but I have yet to find something that works on a Mac. I've tried a "Tehuti networks" 10G copper adapter (which has Mac drivers) but it proved to be too unreliable.
Will the built-in Wifi/BT4 work as a "native handoff, etc."? If the X99-A II had two Ethernet ports, I would probably go that route along with the
osxwifi you indicated. If the Deluxe II Wifi doesn't work like a native Wifi, I will simply disable it and get the osxwifi (I need both Ethernet and Wifi for what I do).
When setting up a RAID through the BIOS, using the "Intel Rapid Storage", will this be seen by the (Mac) OS? This will be for data only. Boot will be off SSD.
Finally, has anybody tried using 3 monitors? I currently use a 27" 4K (DP) and 2 x 27" (HDMI) off a (flashed) GTX 780.
Thanks!
