It doesn't sound like the system is very balanced to me.
It's not surprising it has trouble while trying to support Kinect, voice recognition, video voice chat, gameplay recording, and snapped video streaming / web browsing all at the same time. We already know it takes 10% time of the GPU, how much memory and bandwidth do the other features reserve.
Ironically to get near parity with ps4 you'll probably get games that lock out all the features that set xb1 apart. With all that multitasking on weaker hardware it's never going to catch up.
