ASUS P9X79-E WS vs ASUS Rampage IV Black Edition for new build

[rudyvanbebu]

Hi,

I´m building a new system next week and I still can´t decide on which motherboard to get. I’m now between Asus X79 P9X79-E WS and Asus X79 Rampage IV Black Edition Motherboard. I’ll use any of those with a 4930k, and a GTX 770 or a GTX 780 if the budget allows me
My main concern is if there would be any difference between these two in the PCIe and USB3 compatibility, since I need to assemble them with 2 UAD-2 PCIe cards and the Video Card.
Onboard audio is not important for me, since it will be used with an external audio card.

I know these are not listed as recommended, but I saw in the forum some users with these boards as Actrix, Jaraheel, and flmmkr, if you could share any experience/recommendation or any other situation I may be overlooking, it would be greatly appreciated

Thanks all for your time and help,

The P9X79-E WS has the PCIE compatibility AND it is workstation grade, making it cost more and last longer
