Will a Asus Rampage V mobo be sufficient to power the 150 ohm Game Zero headset by Seinnheiser? Or do I need something else, like the Creative E5 dac at 199$ http/www.amazon.com/Creative-High-Resolution-Headphone-Amplifier-Bluetooth/dp/B00MXJYDUO/ref=sr_1_1?ie=UTF8&qid=1451253946&sr=8-1&keywords=sound+blaster+e5 (pretty pricey) or a sound card? I have a old creative titanium and titanium fatality, but they are 5.0 surround sound dolby, etc.. very old. My issue with a soundcard in general is that I don't really have the space due to the size of my gpu x2 and design of the power supply in the case.
