I have an Asus Rampage 4 Extreme with an i7 3960x CPU that I put together back in November. I just saw something about VT-d not being enabled on the first batch of CPUs. A C2 stepping came out in early 2012 to replace the early chips. I am not overclocking currently. Is the lack of VT-d a big deal for this CPU? I am not sure if this is a major issue or not. Thanks.
