Though the X99E-ITX/ac did suffer a small loss in Photoshop's OpenCL-optimized filters and took a small lead in Adobe Premiere, its overall performance appears average.
We do need to reveal a trick though: we had to change the memory to get a decent time in Adobe After Effects. The reason is that this benchmark needs more than 8GB of RAM, and our modules are 4GB each. By using the same RAM in both dual- and quad-channel tests, the dual-channel board suffers half the bandwidth and half the capacity. That's even less fair than different RAM, but if you want to know, the completion time for this test slowed from 20 seconds to 73 seconds when crippled by an 8GB capacity.
