I have a one month old high spec machine based on Ivy Bridge. I tried everything, and K/Ubuntu 12.01 simply kept freezing at random times. It was a system wide freeze, even the mouse cursor didn't move. I google'ed around, and I was not the only one experiencing this with 12.01.
Have you run burn in and RAM tests on your new machine?
It may just be me, but the last two desktop machines I built for myself had RAM problems. The last one was pretty sneaky because it was able to complete a full Windows installation without an error. It was some problem with triple-channel configuration because each stick tested perfectly fine by itself.
You might also have a heat problem. Perhaps the CPU, the video card or maybe some other motherboard chip.
Speaking of video cards, you can end up getting a bad one. It does happen sometimes that a card may have a defective processor, bad RAM or a badly installed heatsink. Or if it's a gaming card, it may be overclocked beyond what it can really handle.

Your hardware must be very special or your installation is broken. I've been using unity on multiple computers without issue for quite a while.
